When GTK 4 is installed concurrently with GTK 3, importing Gtk will
result in GTK 4 being loaded. However, GTK 3 will be required later

Requiring namespace 'Gtk' version '3.0', but '4.0' is already loaded
To prevent this from happening, explicitly require GTK 3 until the app
is ported to support GTK 4.
