    desktop: add <release> tag for 2.99.12.
    
    It's better to start early as these need to be translated too and are
    now even visible in GIMP itself.
    
    Note that I wrote 2.99.11 in the version attribute, but only to be able
    to test this easily during development. It will have to be edited to the
    right version at release.
