[flake8-pyi] Expand Optional[A] to A | None (PYI016) (#18572)
## Summary
Under preview 🧪 I've expanded rule `PYI016` to also flag type
union duplicates containing `None` and `Optional`.

## Test Plan
Examples/tests have been added. I've made sure that the existing
examples did not change unless preview is enabled.

## Relevant Issues
* https://github.com/astral-sh/ruff/issues/18508 (discussing
introducing/extending a rule to flag `Optional[None]`)
* https://github.com/astral-sh/ruff/issues/18546 (where I discussed this
addition with @AlexWaygood)
