[feanil]

This repository is a depedency of edx-platform and needs to be upgraded to Python 3.11 before
the Readwood release is cut (mid-April).

• Requirements are compiled with Python 3.8
• Tests are run on Python 3.8 and 3.11
• (Optional) Tests are also run with 3.12 and passing or 3.12 issues are ticketed.
• Classifiers in setup.py setup.cfg or pyproject.toml indicate Python 3.11 support
• A new version is release to PyPI
• A PR is merged to edx-platform to use the new version

@feanil, I completed all the steps except for the last one. The version in edx-platform should be automatically updated by the requirements bot, right?
