STY: pin ruff version exactly and fix new violations in v0.16.0

errors are unrelated and addressed in #410.
Note that both PRs include updates to helper scripts (and consequently to their hashes), which will necessarily lead to some merge conflicts. I advise merging one, then rebase/update the other one.

we can also explicitly select the old default ruff rules and add in the new ones one at a time, like in spacetelescope/romancal#2400; the docs say the pre-0.16.0 default rules were:

select = ["E4", "E7", "E9", "F"]

[neutrinoceros]

That'd be fine with me, just not guaranteed to work through future (implicit) upgrades. Let me know what you prefer. In the mean time, I'll just resolve merge conflicts.

[zacharyburnett]

ok then, lets go with the new default rules that ship with 0.16.0, they seem sensible enough and don't introduce too many changes
