Make reviewer per languages

[item4]

I'm working on ko-KR translation. But I'm not sure is my translation correct. I need reviewer for ko-KR translation.

Maybe other worker also needs reviewer. I think we must need at least 2 reviewers per languages.

and I think we needs slack channel for converstation between translators. for example, ko-KR translator need #website-ko

Hello @item4, feel free to present this idea in slack.

As a general rule, I'd recommend only working on translations thatbthe contributor speaks fluently.
