docs: fix Chinese docs to make it more readable

[crazywhalecc]

I also started using FrankenPHP as a test server, but I find that a lot of improvements are needed in the documentation. My improvements do not involve modifications to the document content, just updates to more localized expressions and section formats.

• The Chinese Markdown format is based on Chinese Markdown Writing Standard and another extended guide.
• Fix some format (e.g. special markdown block cannot be translated: [!提示] -> [!TIP]).
• Some linked sites offer Chinese versions.
• Some English expressions cannot be translated directly into Chinese, so English is retained (this is consistent with the context).
