python3-pygobject: RDEPENDS on gobject-introspection

python3-pygobject: RDEPENDS on gobject-introspection

Since 3.51.0, python3-pygobject depends on libgirepository 2.0 provided
by glib-2.0 instead of libgirepository 1.0 provided by
gobject-introspection[1]. It still needs the typelib files from
libgirepository-1.0 package. Add gobject-introspection as a runtime
dependency.

Fixes:

gi.RepositoryError: Typelib file for namespace 'xlib', version '2.0' not found

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<python-input-1>", line 1, in <module>
    from gi.repository import Gtk
  File "/usr/lib64/python3.13/site-packages/gi/importer.py", line 141, in create_module
