Lint Autofix CI Demo

WIP

A demo of a GitHub Actions setup that automatically fixes PRs of external contributors.

Using pull_request_target to elevate your permissions to push to a contributor's fork is unsafe according to GitHub Security Labs best practices.

For security reasons, the process is split in 2 workflows:

• a pull_request workflow that safely runs on the untrusted PR, and only generates a git diff patch
• a workflow_run workflow with elevated permissions that push the diff patch to the repository
