GitHub Action for dotnet format

Run dotnet format as part of your workflow to report formatting errors or auto fix violations as part of your pull request workflow.

Usage

Running on `pull_request`, adding a commit to the PR.

Use this only when the PRs are coming from the same repository. You won't have permission to add commits to PRs coming from a forked repository.
