Automatically run auto-formatter changes during gitlab-ci

It would be nice if our CI/CD system would run a given auto-formatter when a commit is pushed to GitLab so that formatters do not have to be installed and run manually on a user's development environment every time before pushing code.

This should be a quality of life improvement for development and also reduce bloat in our commit history with excessive "run auto-formatter" commits (especially for new developers).

Implementing this may require some kind of Server hook as explained in this Stack Overflow post, or this pre-commit hook via this post.

NOTE: Some posts recommend against running an automated script that forces code changes after commit - some preliminary investigation into whether or not automated server-side (GitLab) reformatting is recommended practice should be done first.
