• [x] I have paid attention to this example and will edit again if need be to not break the formatting, or I will be ignored
• [x] I have searched existing issues to see if the issue has already been opened, and I have checked the commit log to see if the issue has been resolved since my server was last updated
• [x] I have read and understood the Contributing Guide

Describe the feature

I just saw this:

LGTM.com will be shut down in December 2022 — we recommend that you use GitHub code scanning instead.

I guess we'll need to update stuff

How sad, what acronym are we gonna be able to use now? GHCS doesn't have the same ring to it as LGTM does!
