    tests: Don't fail when Gtk+-4.0 is available
    
    We currently link with Gtk+-3.0, so that is the only version we can
    import without conflicts. As without version, gobject-introspection
    will pick the latest available version and Gtk+-4.0 may now be
    available, we thus need to explicitly request the correct version.
