    audio-video-properties:fix string not translatable
    
    "Frames per second" string in audio-video-properties tab was unavailable for translation.
    
    To fix this, handle the string with g_dngettext() and allow for both singular and plural translation.
    
    Closes https://gitlab.gnome.org/GNOME/nautilus/issues/990
