Workaround needed comps change for KF6 rebuild
    
    https://pagure.io/fedora-comps/pull-request/920 is a required
    comps change now
    https://bodhi.fedoraproject.org/updates/FEDORA-2023-ad16578136
    landed in stable, but it won't be in the public comps data till
    after the next compose. This reproduces the same effect on the
    fly in the KDE kickstart when doing the KDE live image build
    test, so it will pass.
