    Revert "ci: Import run-eslint script from gnome-shell"
    
    Filtering errors by changed lines in a merge request means some
    errors can slip through, for example when an import becomes unused
    but isn't removed.
    
    That's more common than rules changing behind our back, so revert
    to running eslint directly again.
