Fix: link to Chinese version should not be broken
The link to the Chinese version (中文版) on the main page is broken. It links to a non-existent /zh-CN/ path.
The main Chinese fork of this project is https://wangchujiang.com/reference/. At least as far as I can tell - it was created explicitly to translate https://cheatsheets.zip/ and has the appropriate link-backs. Although the the code-bases have clearly diverged, it still seems to be the most appropriate link to use.
I have updated the link accordingly.
@Fechin is this correct/desired link? Or should the broken link be removed instead? Let me know and I can update the PR if required.
I notice the link to the Chinese version has been removed in the recent UI component refactor, so this PR is now obsolete
