Create Fedora 41 pages (index, blocking, spins)
    
    This includes several updates to the release-blocking image list.
    The Workstation size is bumped to 2.5 GB as per the WG's request
    in https://bugzilla.redhat.com/show_bug.cgi?id=2276839 and the
    blocker review meeting today. Several filenames are corrected to
    match those produced by our current builder tools.
