Merge pull request #786 from ipfs-shipyard/fix/chinese-translation

Rename Locale for Chinese (China) to zh-CN 

Received some useful hints from our friends at Transifex and I think this approach is the  way to go forward.

This PR applies revised naming convention from ipfs/ipfs-gui#50 (comment)  and renames Chinese locale from `zh` to `zh-CN`,  which is supported by `i18next` and match value from `Accept-Language`

I smoke tested this PR and strings that are already translated rendered correctly.

In the future we can add `pt-BR` and  `en-GB` using the same convention :)
