    ci: Check for issue/MR URLs in commit messages
    
    Commit messages should include the full URL to an issue or merge
    request to keep associated information easily available in future
    log digging.
    
    Jonas came up with a script to enforce that policy for mutter and
    gnome-shell. It's an excellent idea, so adopt it here as well.
