Ensure setuptools, wheel, and pip is present when initializing environment when using uv

Unfortunately, doesn't seem to help with a fresh tox and virtual environment.
I'm on Ubuntu 22.04.4 LTS and seeing tests succeed on 3.8 & 3.9 but fail on 3.11 and 3.12 in tox.

I can also replicate outside of tox.

Creating a new venv where setuptools and wheel are not pre-installed. Install pytest, requirements.txt and tests/requirements.txt. Run python -m pytest.

Unclear why tests are passing using tox in the pipeline here.

I can still replicate the issue with:

docker run --rm -ti -v .:/src --entrypoint bash python:3.12-slim

apt update
apt install git
cd /src
python -m venv venv
source venv/bin/activate
pip install pytest
pip install -r requirements.txt
pip install -r tests/requirements.txt
python -m pytest

pip install tox
python -m tox -e py
