During today's GitHub Actions outage, it became apparent that we need an easy way to push to production with a CLI command.

This can be easily accomplished by checking out the current master branch and then force pushing to the production branch, triggering a manual build on the CD environment. I'm going to close this as there's an easy way to do this and there's no need for a manual script to be added at this time.
