    installed-media: Make it easier to test the GNOME Nightly images
    
    The GNOME Nightly VM images are currently produced as GitLab CI
    jobs, and therefore available for a limited amount of time to be
    downloaded.
    
    This way, we now launch a File Chooser to allow users to pick the
    VM image.
    
    https://gitlab.gnome.org/GNOME/gnome-build-meta/issues/208
    
    Fixes #419
