Update pyproject.toml

Proposing 2 changes to the TOML:

1. The strict version requirement for bespokelabs-curator was failing for me; I'd suggest relaxing it if possible.
2. LiveBench has an additional dependency, PyExt. Unfortunately this is a very old package and the latest mainline release isn't compatible with post 3.10 versions of Python. I forked it and created a new release which should be compatible with 3.11 and up, and added it to the TOML.
