Solution for different translation in zh-HK and zh-TW

Actually, we can translate messages to zh-hk, but as far as I've asked in phab:T170836, there's collaboration problems that no repositories can update their zh-hk messages, need more suggestions on this problem.

Now we can translate to zh-HK, right?

zh-HK is enabled yes. Only messages that require different translations should be translated.
