[frogr] Use gvfs-open instead of xdg-open when GAppInfo could not be used

    Use gvfs-open instead of xdg-open when GAppInfo could not be used
    
    This works better since gvfs-open uses g_app_info_launch_default_for_uri()
    under the hood, which will hook into the OpenURI portal logic, allowing
    frogr to authorize accounts and open external viewers when running inside
    of a flatpak sandbox.
