    build: fix Windows installer
    
    The Hungarian language file for the Windows installer was recently moved
    from unofficial to the officially supported languages. However, a new
    release including Hungarian by default is not available yet. This causes
    our CI to fail because it can't find Hungarian in unofficial.
    
    We change our ci script to download Hungarian from the correct location
    for official languages, and adapt gimp3264.iss to reflect the correct
    location.
