[Xu-Justin]

Summary

This pull request add a note for user to build this project using Python 3.12 or earlier.

---

Python deprecated the functions PyEval_ThreadsInitialized() in Python 3.9, and completely removed them in Python 3.13

If you attempt to build the library using Python 3.13, you'll encounter an error like this:
