[pylint] Implement invalid-hash-returned (PLE0309)

[tibor-reiss]

Add pylint rule invalid-hash-returned (PLE0309)

See #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 invalid-index-returned), ruff will raise, compared to pylint which will not raise."
