updates the dependency PyExt for python3.11\3.12 support

[ShaohonChen]

Description

This PR updates the dependency PyExt to use a pyext compatibility fork that supports Python 3.10, 3.11, and 3.12, ensuring compatibility with modern Python versions while maintaining existing functionality.

The original PyExt package was incompatible with Python 3.10+, causing runtime errors below:

hint: See above for details.

Note: I’ve also submitted a PR to the original PyExt repository (refi64/PyExt#5) to address these issues upstream, including previously overlooked ipykernel support. This fork serves as an interim solution until upstream merges the changes.
