What does this PR do?

This PR adds the Chinese translation of the "References" configuration documentation.
I translated the original English document sentence by sentence, preserving all formatting, code blocks, and structure, and placed the translated file into the Chinese documentation directory (e.g. docs/zh/ or equivalent).

The translation covers local directory references, Git repository references, usage descriptions, hidden autocomplete entries, and the full configuration fields table.

How did you verify your code works?

• Rendered the Markdown locally to confirm all formatting, tables, and code blocks display correctly.
• Compared side-by-side with the original English doc to ensure every sentence is translated without omissions.
• Checked that all internal links and note admonitions are preserved.

Screenshots / recordings

This is a documentation-only change, no UI screenshots needed.
