Update action.yml

This partially fixes #940 by updating the description to match the request. However I'm assuming the runner adds in the `Action` part by truncating the description? cc @bryanmacfarlane

-This action checks-out your repository under `$GITHUB_WORKSPACE`, so your workflow can access it.
-
-Only a single commit is fetched by default, for the ref/SHA that triggered the workflow. Set `fetch-depth: 0` to fetch all history for all branches and tags. Refer [here](https://help.github.com/en/articles/events-that-trigger-workflows) to learn which commit `$GITHUB_SHA` points to for different events.
-
-The auth token is persisted in the local git config. This enables your scripts to run authenticated git commands. The token is removed during post-job cleanup. Set `persist-credentials: false` to opt-out.
-
-When Git 2.18 or higher is not in your PATH, falls back to the REST API to download the files.

-
-## Checkout multiple repos (side by side)
-

-```
-
-## Checkout multiple repos (nested)
-
-```yaml
-- name: Checkout
-  uses: actions/checkout@v2
-
-- name: Checkout tools repo
-  uses: actions/checkout@v2
-  with:
-    repository: my-org/my-tools
-    path: my-tools
-```
-
-## Checkout multiple repos (private)
-
-```yaml
-- name: Checkout

-    repository: my-org/my-private-tools
-    token: ${{ secrets.GitHub_PAT }} # `GitHub_PAT` is a secret that contains your PAT
-    path: my-tools
-```
-
-> - `${{ github.token }}` is scoped to the current repository, so if you want to checkout a different repository that is private you will need to provide your own [PAT](https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line).

-# ADR 0153: Checkout v2
-
-**Date**: 2019-10-21
-
-**Status**: Accepted
-
-## Context
-
-This ADR details the behavior for `actions/checkout@v2`.
-
-The new action will be written in typescript. We are moving away from runner-plugin actions.
-
-We want to take this opportunity to make behavioral changes, from v1. This document is scoped to those differences.
-
-## Decision
-
-### Inputs
-
-```yaml
-  repository:
-    description: 'Repository name with owner. For example, actions/checkout'
-    default: ${{ github.repository }}
-  ref:
-    description: >
-      The branch, tag or SHA to checkout. When checking out the repository that
-      triggered a workflow, this defaults to the reference or SHA for that
-      event.  Otherwise, defaults to `master`.
-  token:
-    description: >
-      Personal access token (PAT) used to fetch the repository. The PAT is configured
-      with the local git config, which enables your scripts to run authenticated git
-      commands. The post-job step removes the PAT.
-
-
-      We recommend using a service account with the least permissions necessary.
-      Also when generating a new PAT, select the least scopes necessary.

-    default: false
-```
-
-Note:
-- SSH support is new
-- `persist-credentials` is new
-- `path` behavior is different (refer [below](#path) for details)
-
-### Fallback to GitHub API
-
-When a sufficient version of git is not in the PATH, fallback to the [web API](https://developer.github.com/v3/repos/contents/#get-archive-link) to download a tarball/zipball.
-
-Note:
-- LFS files are not included in the archive. Therefore fail if LFS is set to true.
-- Submodules are also not included in the archive.
-
-### Persist credentials
-
-The credentials will be persisted on disk. This will allow users to script authenticated git commands, like `git fetch`.
-
-A post script will remove the credentials (cleanup for self-hosted).
-
-Users may opt-out by specifying `persist-credentials: false`
-
-Note:
-- Users scripting `git commit` may need to set the username and email. The service does not provide any reasonable default value. Users can add `git config user.name <NAME>` and `git config user.email <EMAIL>`. We will document this guidance.
-
-#### PAT
-
-When using the `${{github.token}}` or a PAT, the token will be persisted in the local git config. The config key `http.https://github.com/.extraheader` enables an auth header to be specified on all authenticated commands `AUTHORIZATION: basic <BASE64_U:P>`.
-
-Note:
-- The auth header is scoped to all of github `http.https://github.com/.extraheader`
-  - Additional public remotes also just work.
-  - If users want to authenticate to an additional private remote, they should provide the `token` input.
-
-#### SSH key
-
-The SSH key will be written to disk under the `$RUNNER_TEMP` directory. The SSH key will
-be removed by the action's post-job hook. Additionally, RUNNER_TEMP is cleared by the
-runner between jobs.
-
-The SSH key must be written with strict file permissions. The SSH client requires the file
-to be read/write for the user, and not accessible by others.
-
-The user host key database (`~/.ssh/known_hosts`) will be copied to a unique file under
-`$RUNNER_TEMP`. And values from the input `ssh-known-hosts` will be added to the file.
-
-The SSH command will be overridden for the local git config:
-
-```sh
-git config core.sshCommand 'ssh -i "$RUNNER_TEMP/path-to-ssh-key" -o StrictHostKeyChecking=yes -o CheckHostIP=no -o "UserKnownHostsFile=$RUNNER_TEMP/path-to-known-hosts"'
-```
-
-When the input `ssh-strict` is set to `false`, the options `CheckHostIP` and `StrictHostKeyChecking` will not be overridden.
-
-Note:
-- When `ssh-strict` is set to `true` (default), the SSH option `CheckHostIP` can safely be disabled.
-  Strict host checking verifies the server's public key. Therefore, IP verification is unnecessary
-  and noisy. For example:
-  > Warning: Permanently added the RSA host key for IP address '140.82.113.4' to the list of known hosts.
-- Since GIT_SSH_COMMAND overrides core.sshCommand, temporarily set the env var when fetching the repo. When creds
-  are persisted, core.sshCommand is leveraged to avoid multiple checkout steps stomping over each other.
-- Modify actions/runner to mount RUNNER_TEMP to enable scripting authenticated git commands from a container action.
-- Refer [here](https://linux.die.net/man/5/ssh_config) for SSH config details.
-
-### Fetch behavior
-
-Fetch only the SHA being built and set depth=1. This significantly reduces the fetch time for large repos.
-
-If a SHA isn't available (e.g. multi repo), then fetch only the specified ref with depth=1.
-
-The input `fetch-depth` can be used to control the depth.
-
-Note:
-- Fetching a single commit is supported by Git wire protocol version 2. The git client uses protocol version 0 by default. The desired protocol version can be overridden in the git config or on the fetch command line invocation (`-c protocol.version=2`). We will override on the fetch command line, for transparency.
-- Git client version 2.18+ (released June 2018) is required for wire protocol version 2.
-
-### Checkout behavior
-
-For CI, checkout will create a local ref with the upstream set. This allows users to script git as they normally would.
-
-For PR, continue to checkout detached head. The PR branch is special - the branch and merge commit are created by the server. It doesn't match a users' local workflow.
-
-Note:
-- Consider deleting all local refs during cleanup if that helps avoid collisions. More testing required.
-
-### Path
-
-For the mainline scenario, the disk-layout behavior remains the same.
-
-Remember, given the repo `johndoe/foo`, the mainline disk layout looks like:
-
-```
-GITHUB_WORKSPACE=/home/runner/work/foo/foo
-RUNNER_WORKSPACE=/home/runner/work/foo
-```
-
-V2 introduces a new contraint on the checkout path. The location must now be under `github.workspace`. Whereas the checkout@v1 constraint was one level up, under `runner.workspace`.
-
-V2 no longer changes `github.workspace` to follow wherever the self repo is checked-out.
-
-These behavioral changes align better with container actions. The [documented filesystem contract](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/virtual-environments-for-github-hosted-runners#docker-container-filesystem) is:
-
-- `/github/home`
-- `/github/workspace` - Note: GitHub Actions must be run by the default Docker user (root). Ensure your Dockerfile does not set the USER instruction, otherwise you will not be able to access `GITHUB_WORKSPACE`.
-- `/github/workflow`
-
-Note:
-- The tracking config will not be updated to reflect the path of the workflow repo.
-- Any existing workflow repo will not be moved when the checkout path changes. In fact some customers want to checkout the workflow repo twice, side by side against different branches.
-- Actions that need to operate only against the root of the self repo, should expose a `path` input.
-
-#### Default value for `path` input
-
-The `path` input will default to `./` which is rooted against `github.workspace`.
-
-This default fits the mainline scenario well: single checkout
-
-For multi-checkout, users must specify the `path` input for at least one of the repositories.
-
-Note:
-- An alternative is for the self repo to default to `./` and other repos default to `<REPO_NAME>`. However nested layout is an atypical git layout and therefore is not a good default. Users should supply the path info.
-
-#### Example - Nested layout
-
-The following example checks-out two repositories and creates a nested layout.
-
-```yaml
-# Self repo - Checkout to $GITHUB_WORKSPACE
-- uses: checkout@v2
-
-# Other repo - Checkout to $GITHUB_WORKSPACE/myscripts
-- uses: checkout@v2
-  with:
-    repository: myorg/myscripts
-    path: myscripts
-```
-
-#### Example - Side by side layout
-
-The following example checks-out two repositories and creates a side-by-side layout.
-
-```yaml
-# Self repo - Checkout to $GITHUB_WORKSPACE/foo
-- uses: checkout@v2
-  with:
-    path: foo
-
-# Other repo - Checkout to $GITHUB_WORKSPACE/myscripts
-- uses: checkout@v2
-  with:
-    repository: myorg/myscripts
-    path: myscripts
-```
-
-#### Path impact to problem matchers
-
-Problem matchers associate the source files with annotations.
-
-Today the runner verifies the source file is under the `github.workspace`. Otherwise the source file property is dropped.
-
-Multi-checkout complicates the matter. However even today submodules may cause this heuristic to be inaccurate.
-
-A better solution is:
-
-Given a source file path, walk up the directories until the first `.git/config` is found. Check if it matches the self repo (`url = https://github.com/OWNER/REPO`). If not, drop the source file path.
-
-### Submodules
-
-With both PAT and SSH key support, we should be able to provide frictionless support for
-submodules scenarios: recursive, non-recursive, relative submodule paths.
-
-When fetching submodules, follow the `fetch-depth` settings.
-
-Also when fetching submodules, if the `ssh-key` input is not provided then convert SSH URLs to HTTPS: `-c url."https://github.com/".insteadOf "git@github.com:"`
-
-Credentials will be persisted in the submodules local git config too.
-
-### Port to typescript
-
-The checkout action should be a typescript action on the GitHub graph, for the following reasons:
-- Enables customers to fork the checkout repo and modify
-- Serves as an example for customers
-- Demystifies the checkout action manifest
-- Simplifies the runner
-- Reduce the amount of runner code to port (if we ever do)
-
-Note:
-- This means job-container images will need git in the PATH, for checkout.
-
-### Branching strategy and release tags
-
-- Create a servicing branch for V1: `releases/v1`
-- Merge the changes into `master`
-- Release using a new tag `preview`
-- When stable, release using a new tag `v2`
-
-## Consequences
-
-- Update the checkout action and readme
-- Update samples to consume `actions/checkout@v2`
-- Job containers now require git in the PATH for checkout, otherwise fallback to REST API
-- Minimum git version 2.18
-- Update problem matcher logic regarding source file verification (runner)
