DOC: Add Chinese version of README (README_zh.md)

[xingyubobo33333]

Pandas version checks

• I have checked that the issue still exists on the latest versions of the docs on main here

Location of the documentation

https://pandas.pydata.org/README.md

Documentation problem

The pandas official repository currently only provides an English README, creating a language barrier for Chinese-speaking users to understand core project information.

Suggested fix for documentation

I propose adding a README_zh.md that strictly aligns with the structure of the English README and follows technical terminology standards, thereby enhancing the friendliness for the Chinese community.

Hi! I’m new to the project and I’d love to help with this issue.
If no one is working on it yet, may I take it and try to help?
