    ci: install cjk fonts needed for quickreference pdf
    
    The quickreference pdf translations for ko, ja, and zh_CN were not showing
    the correct CJK characters.
    
    So let's install a fonts package that gives us support for these
    characters.
    Also build Japanese, this way we will know when building translations
    fails.
