Have container-nightly.sh publish all container images
    
    What container-nightly.sh does to publish container images is
    currently inconsistent across branches. #1267 made it publish
    only the regular container images (the ones it actually builds)
    on the f39 branch. On f40 and main branches, it currently would
    not publish the images it builds at all, it instead only
    runs sync-ostree-base-containers.sh , which converts the ostrees
    for some of the atomic desktops to OCI images and publishes
    those (which is also what it used to do on the f39 branch).
    
    We should make the behavior consistent across all branches. The
    script is never actually run on the 'main' branch, but new
    releases branch off 'main' so we should keep it in line with
    our intentions.
    
    Overall at present, I think the most sensible thing to do is
    have this script run both sync scripts.
    
    The Fedora-Container compose does not build atomic desktop stuff
    at all; Bodhi does that. But Bodhi does not have any ability to
    convert the ostrees it builds to OCI images, natively produce
    OCI images, or publish OCI images to registries. So if we don't
    have something else do that, we will never publish updated OCI
    images for atomic desktops for stable releases. Since we ought
    to run the script somewhere, doing it here seems as good as
    anywhere.
    
    Longer term we need to make various improvements to this whole
    process, but for now this seems the pragmatic thing to do.
