qreator fails to start because of incorrect gtk import

[Jeremy Bícha]

Impact
------
The qreator app won't run in a default Ubuntu 22.04 LTS install

Test Case
---------
From Ubuntu 22.04 LTS, install qreator
Run qreator

What Could Go Wrong
-------------------
This just adds a patch to add the require_version lines to the gobject-introspection imports. Without this patch, the app tries to load the latest gir bindings for GTK installed which is GTK4 but the app only works with GTK3.

More Info
