Resolve "Devise i18n support"

related to MR on JiHu

What does this MR do and why?

This MR is to achieve I18n international standardization and add the zh_CN language.

• Add devise.zh-cn.yml

  The zh_CN.yml is for zh_CN translation as I18n.

  The file can be placed in any directory (including JH) and loaded into the program via I18n.load_path.

  Not only 'JH' needs to implement zh_CN translation, but also the subsequent upstream. So we should put the file in upstream. (According to the official I18n convention, the file should be placed in the config/locales directory)

• Translation reference

  The zh_CN.ymlis translated according to the en.yml key-value pair format.

  And the translation into zh_CN is based on this link: https://gist.github.com/Artoria2e5/6d2a06ca9e92a417afc627b5000f4690#file-devise-zh-cn-yml
