Description of problem:
With gnome-desktop3-40~alpha the number of keyboard layouts shown
in gnome-control-center seems severely reduced (in a bad way).

Version-Release number of selected component (if applicable):
gnome-desktop3-40~alpha.0-1.fc35

How reproducible:
100%

Steps to Reproduce:
1. boot Fedora-Workstation-Live-x86_64-Rawhide-20210210.n.0.iso
2. in gnome go to Settings -> Region & Language
3. try to add eg a Japanese Input Source

Actual results:
The only keyboard Latin-based keyboard layout listed is Japanese PC-98, which is not used these days, in addition to the expected Japanese input method (Anthy).

Expected results:
standard Japanese layout (JP) to be listed

Additional info:
This doesn't happen with Fedora-Workstation-Live-x86_64-Rawhide-20210208.n.0.iso
which has gnome-desktop3-3.38.3-2.fc34.

I tracked this down at the package list by comparing the package lists in the 20210208.n.0 and 20210210.n.0 composes using pkgtreediff.
Since gnome-desktop3-40~alpha.0-1.fc34 was already built in a sidetag I expect this bug will hit F34 soon.
