Fix translations languages

[mtsfer]

Reference: #868

Also fixes korean language code. The correct one is "ko".

Closes: #854

@mtsfer i think it should be

zh-cn and ko-kr respectively.

zh is the parent language code and cn is sub language code.

@dr5hn I've found this discussion about Chinese variations, and zh-CN is indeed the better option.

However, I wasn't able to find any reliable resource about ko-KR. Based on here, ko is the standard Korean, ko-KP is the North Korea variation and ko-KR is the South Korea variation.

Defaulting to ko while not sure which variation is being used on Korean translations wouldn't be a safer move here?

[dr5hn]

@mtsfer Agree with keeping ko as is and changing zh to zh-cn. Please make required changes and rebase the branch.

Thanks so much for your active participation and all the work you're doing.

[dr5hn]

@mtsfer Could you please rebase you branch and resolve conflicts?

[mtsfer]

@dr5hn Sorry for the late reply. I'm working on this right now.

@dr5hn @mtsfer This PR broke the currency_symbol for a couple of countries using kr. It now says ko instead of kr as it should be, and was before.
