Fix test and doc errors and warnings with most recent dependencies

[tovrstra]

This is just maintenance:

• Update pre-commit hooks
• Use modern Python approach to load IOData's version number in to sphinx
• Fix a warning when builkding the docs
• Replace some outdated pytest constructs in the unit tests
• Upgrade too low build-system dependencies
• Add the worksteal option to pytest for improved unit test concurrency

🟡 Changes recommended

The updated Sphinx autodoc skip logic in docs/conf.py has a concrete correctness gap for imported members that lack __module__, so it may not actually suppress external/imported symbols as intended.

Once you've addressed the issues Copilot identified, you can request another Copilot review.
