Revert "python3-gobject: update to 3.52.3"

This reverts commit 0c02a10c96.

python3-gobject 3.52 switches to using libgirepository in glib, however this
this breaks libpeas-1's python loader plugin, while this is not an issue in
libpeas-2, many applications are still using libpeas-1 with no current plans
to migrate.

Revert for now until upstreams have more time to handle the change.
