Thoughts on switching to dependency groups in pyproject.toml?

[stefmolin]

PEP 735 added dependency groups to pyproject.toml, which would remove the need to have multiple requirements files.

This would allow us to hopefully remove those requirements.txt files and the logic to generate them. For example, in .circleci/config.yml we could make the following change:

- python -m pip install --upgrade -r requirements/doc.txt
+ python -m pip install --upgrade --group doc

Woohoo! Finally. I'm so happy to see this.
