[JamesClarke7283]

Summary

This PR updates the pinned dependencies in the pyproject.toml to support python3.12. this is a first draft.

If we are making use of asyncio in some capacity, it might improve performance a fair amount in some use cases, as a added bonus.

Related Issues / Discussions

Will likely fix #6214 Will also likely fix #5674 although, we may want to add scripts which update the pinned versions to the lowest version that x python version supports, as long as the version is equal to or greater than whats already in the dependencies.
