Port to libgirepository-2.0

Browse source 
pygobject 3.52 has switched [1] to using libgirepository-2.0 which
comes from glib itself now, rather than the 1.0 which came from
gobject-introspection.

This means that it fails to load the incompatible "GIRepository 2.0"
and thus must be ported to 3.0 (which is provided by
libgirepository-2.0).

Migration guide is here [2]

[1]: https://gitlab.gnome.org/GNOME/pygobject/-/merge_requests/320
[2]: https://docs.gtk.org/girepository/migrating-gi.html

This commit adds suppport for importing with
"gi.require_version("GIRepository", "3.0") and falling
back to the existing "GIRepository 2.0" if not found.
