Gnome 40 Support

Created by: hedayat

The extension doesn't work under Gnome 40.

At least. when you try to open the preferences you receive:

TypeError: class heritage Gtk.VBox is not an object or null

Well, it seems that it is because of the move to Gtk 4.

You also need to explicitly add version 40 to extension supported gnome shell versions.

Update: the extension itself seems to also need changes to become compatible with gnome 40 Update 2: well, while it didn't work before, it works fine now. So, it seems that fixing the preferences window is enough to support gnome shell 40.
