WIP: Nightmare scenario warning on redirected deprecated rules

Similar to https://github.com/astral-sh/ruff/pull/9689 — retains removed
rules for better error messages and documentation but removed rules
_cannot_ be used in any context.

Removes PLR1706 as a useful test case and something we want to
accomplish in #9680 anyway. The rule was in preview so we do not need to
deprecate it first.

Closes https://github.com/astral-sh/ruff/issues/9007

## Test plan
