[Ruff 0.5] Stabilise manual-dict-comprehension (PERF403)

[AlexWaygood]

Summary

This rule's been in preview for a very long time (over 9 months, if I'm not mistaken). There are no open issues about it, the docs accurately describe what it does, and the implementation seems sound.

It's an opinionated rule that advocates a micro-optimisation -- but this is true for all the perflint rules, and is flagged in the docs. I don't think you'd enable the PERF category at all if you weren't interested in this kind of rule.

✅ ecosystem check detected no linter changes.

The ecosystem report LGTM. Those indeed could all be replaced with dict comprehensions if you wanted to micro-optimise your code.

I think all ecosystem changes except for the last one would require using dict.update method. This part is documented in the [example section], so seems good to promote to stable.
