Add import sorting

[bmos]

As per last year's discussion in #1132, here is a discrete PR implementing import sorting in the Github Actions check and pre-commit config.

See PEP #8 > Imports
https://peps.python.org/pep-0008/#imports

I think we should use the ruff import sorter rather than bring isort in. Since we're already using ruff and ruff comes with an isort-like import sorter.

Ruff documentation on its import sorter: https://docs.astral.sh/ruff/faq/#how-does-ruffs-import-sorting-compare-to-isort

Ruff documentation on how to use its import sorter: https://docs.astral.sh/ruff/formatter/#sorting-imports

I don't see any conflicts between ruff and isort in the repo as-is, and can't find any description of this, but I know isort and black and have conflicting opinions about how to format imports, and I imagine that could be true for isort and ruff as well.

I think the main value here is reducing additional dependencies, which is a chronic problem with parsons.

How interesting, I had no idea that Ruff offered that.
I completely agree and I will rework this pull request this afternoon.
