Use Gitea over GitLab

Gitea simply offers better performance. I wasn't using all of GitLab's
features anyway, and while the missing CI is annoying, I hadn't
previously managed to set this up anyway, and it can be easily
replaced by something a bit more dedicated than GitLab's
implementation.

This should hopefully allow me to host git repositories without
compromising on memory/CPU time available to other services.
