[Bug 2128423] Default GTK_IM_MODULE should be ibus in GNOME Xorg

https://bugzilla.redhat.com/show_bug.cgi?id=2128423

--- Comment #1 from Jens Petersen  ---
This means in particular that if you try to add a first input method in
gnome-control-center
you need to restart gnome in order for it to work properly, which is not a
great experience
(unlike in Wayland where the input method just works immediately).

Strictly speaking this regression started actually in F36 (Gnome 42) I believe.
But we feel it is actually a potential blocker bug.

Though this is not resolved yet upstream.
