Embed applications into the Silverblue installer image (Rawhide)
    
    A long-term goal of Silverblue has been moving applications that
    were previously part of the Workstation image into Flatpaks.
    At this point, we many of the applications that were removed from
    Silverblue available as Fedora Flatpaks, and we have the necessary
    Anaconda support, so we should update the Silverblue images to include
    the runtime and applications.
    
    This is currently x86_64 only, since we don't have a working OSBS
    cluster to build containers for aarch64 or ppc64le.
    
    Note that Fedora Flatpaks are single-stream, so this embeds the
    F30 runtime and applications into the Rawhide installer image. When
    the applications are released for F31, the embedded runtime will
    need to be updated.
