[`flake8-comprehensions`] Stabilize `unnecessary-dict-comprehension-for-iterable` (`C420`) (#16624) ## Summary Stabilizes C420 for the 0.10 release. ## Test Plan No open issues or PRs (except a general issue about [string normalization](https://github.com/astral-sh/ruff/issues/16579)). The last (and only) false-negative bug fix was over a month ago. The tests for this rule were already not on the `preview_rules` test, so I just changed the `RuleGroup`. The documentation looked okay to me.
