[gnomemm-website] Mark images as non-translatable

[Kjell Ahlstedt <kjellahl src gnome org>]

commit af9244178c1f0bf17dac38a9f10652d81624f570
Author: Kjell Ahlstedt <kjell ahlstedt bredband net>

    Mark images as non-translatable
    
    The images gtk-logo.png and GNOME-logo.png don't contain text. Mark them as
    non-translatable. If they are translatable, they result in broken links on
    https://l10n.gnome.org/module/gnomemm-website/site/master/<lang>/images/.
    Bug #748470.
