[pylint] Implement invalid-length-returned (E0303) (#10963)

Browse source 
Add pylint rule invalid-length-returned (PLE0303)

See https://github.com/astral-sh/ruff/issues/970 for rules

Test Plan: `cargo test`

TBD: from the description: "Strictly speaking `bool` is a subclass of
`int`, thus returning `True`/`False` is valid. To be consistent with
other rules (e.g.
[PLE0305](https://github.com/astral-sh/ruff/pull/10962)
invalid-index-returned), ruff will raise, compared to pylint which will
not raise."
