Remove end-of-support python 3.9

[bmos]

Python 3.9 was first released 2020-10-05. It reaches official end-of-support 2025-10.
I'd suggest we remove support for Python 3.9 in December or Q1 2026 (to avoid negatively impacting Nov elections).

Closes #1519

Remove 3.9 support
Update python syntax to 3.10+ (No more Literal or Union imports! and add strict=False to zip())
Remove conditional dependencies only used for python <3.10
Update ruff command in pre-commit to resolve warning

All syntax changes required to merge old PRs into main after this is merged can be be handled by ruff check --fix
