[`pylint`] Add PLE1141 `DictIterMissingItems` (#9845)
## Summary
References https://github.com/astral-sh/ruff/issues/970.
Implements
[`dict-iter-missing-items`](https://pylint.readthedocs.io/en/latest/user_guide/messages/error/dict-iter-missing-items.html).
Took the tests from "upstream"
[here](https://github.com/DanielNoord/pylint/blob/main/tests/functional/d/dict_iter_missing_items.py).
~I wasn't able to implement code for one false positive, but it is
pretty estoric: https://github.com/pylint-dev/pylint/issues/3283. I
would personally argue that adding this check as preview rule without
supporting this specific use case is fine. I did add a "test" for it.~
This was implemented.
## Test Plan
Followed the Contributing guide to create tests, hopefully I didn't miss
any.
Also ran CI on my own fork and seemed to be all okay 😄
~Edit: the ecosystem check seems a bit all over the place? 😅~ All good.
