Python Version Compatibility

[arthaszyb]

What happened?

There is a fault while pip installs autoGen with the Python versions higher than 3.12. But the current reminder only point to the versions below 3.10.

raise CompileError(msg)
distutils.errors.CompileError: command '/usr/bin/clang++' failed with exit code 1

note: This error originates from a subprocess, and is likely not a problem with pip.

What did you expect to happen?

Python version compatibility issue.

How can we reproduce it (as minimally and precisely as possible)?

1. Remark the compatible Python version range in the README doc.
2. Ensure compatibility with future major versions of Python.

This is due to the grpcio dependency not having wheels built for 3.13 and the source build subsequently failing. To fix this we'll need to upgrade grpcio to at least 1.66. This is important but will need to be taken on as a task to ensure xlang is still working.
