Fix linter

Ruff now checks for B905, i.e. it wants to use strict=True in zip. I guess I understand why this would be a sensible thing to do, but we violate this in so many places in the code that I prefer to just not check for it.
If you disagree, I can go through all instances of zip and add the keyword, of course. Please checkout the above link to the ruff website before deciding.

Uh.. sounds like a good thing to have strict=true, doesn't it?
