Translate README to Chinese

[nmdias]

Chinese is the #1 spoken language in the world and I'd love to have InfoKit be more inclusive, unfortunately I don't speak Chinese. If you know Chinese, and would like to help out, I'd be eternally grateful.

Pull Requests to the README.zh-CN.md are super welcome

Thank you 🙏
