This action checks-out your repository under `$GITHUB_WORKSPACE`, so your workflow can access it.
Only a single commit is fetched by default, for the ref/SHA that triggered the workflow. Set `fetch-depth` to fetch more history. Refer [here](https://help.github.com/en/articles/events-that-trigger-workflows) to learn which commit `$GITHUB_SHA` points to for different events.

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.
