[gnome-control-center/wip/hadess/handle-logo-dark] info-overview: Make sure -dark non-text logo variant is handled

[Bastien Nocera <hadess src gnome org>]

    info-overview: Make sure -dark non-text logo variant is handled
    
    gtk_image_set_from_icon_name() would fallback from $LOGO-text-dark to
    $LOGO-text to $LOGO, leaving out $LOGO-dark which might be available.
    
    Make sure it's in the list of possibilities by using
    g_themed_icon_new_from_names() and listing it explicitly as a possible
    icon name instead.
    
    Fixes: a3b8964a1936274dc4021455648d51edb11b520d
    Closes: #1415
