pin to requests 2.31 to resolve docker library error

[pyth0n1c]

This morning, python requests library 2.32 was pushed.
However, this breaks docker-py: docker/docker-py#3256

Since docker-py is a dependency, we must pin to request ~2.31 for now

We also have added setuptools, which is not installed by default in Python 3.12: Link to Python 3.12 release notes
To pyproject.toml since it is used in pycvesearch: https://github.com/cve-search/PyCVESearch/blob/6a492a72f95ea96f1ef56109d138dfa344d7e9ec/pycvesearch/core.py#L4

requests 2.32.0 and 2.32.1 were both yanked with 2.32.2 being the new release. However, I believe we actually need docker-py's next release which includes a more stable fix. That release appears to be in-progress (docker/docker-py#3262) but is not yet available.

Merging this query and then will create another PR when a more stable fix is out!
