Access values using action outputs

[rlespinasse]

In addition to the environment variables, we want to access the values as action outputs.

- id: git-commit-data
  name: Expose git commit data
  uses: rlespinasse/git-commit-data-action@v1
- run: |
     echo "${{ steps.git-commit-data.outputs.sha }} is the same as ${{ env.GIT_COMMIT_SHA }}"
     echo "${{ steps.git-commit-data.outputs.author }} is the same as ${{ env.GIT_COMMIT_AUTHOR }}"

The publish-env input (as boolean) enables us to disable the publication as an environment variable.

⚠️ about the multiline environment variable. We may need to use javascript (github-script) to support this usecase.
