    ci: Add a fedora build job
    
    We currently use a setup modelled after the flatpak CI workflow,
    where we produce extension bundles and expose them as artifacts
    for easy testing.
    
    It still makes sense to test a regular build though, in particular
    as that can include classic mode support.
