[ruff] Implement none-not-at-end-of-union (RUF036)

[sbrugman]

Summary

Resolves #14290.

Naming pattern inspired by https://docs.astral.sh/ruff/rules/module-import-not-at-top-of-file/.

This rule would greatly benefit from an autofix, but that's for a follow-up PR.

Test Plan

cargo test and reviewed the ecosystem results (all good).
