ci: Pin Python version to at least 3.10 for LiteLLM

[alexander-alderman-webb]

Update our test matrix with new releases of integrated frameworks and libraries.

How it works

• Scan PyPI for all supported releases of all frameworks we have a dedicated test suite for.
• Pick a representative sample of releases to run our test suite against. We always test the latest and oldest supported version.
• Update tox.ini with the new releases.
