Pushed now.

The reason this took so long was because the ibus registry really hates
me.  See also <https://issues.guix.gnu.org/22707>.  The series of
command that led me to success was

$ rm ~/.cache/ibus -rf
$ ibus write-cache
$ pkill ibus
$ ibus-setup

Note that this was more or less required thanks to a stale cache and
not due to the lack of GTK4 support; the GTK4 support just makes it so
that GTK4 apps can actually use ibus.

Hopefully there's a more sane way to do this and hopefully this isn't
required per reboot.

Cheers
