Affected: crates.io: libcrux-ml-dsa

The AVX2 implementation of ML-DSA verification incorrectly implemented the `use_hint` function, mishandling an edge case that should lead to signature rejection.

## Impact An attacker could make the ML-DSA verifier accept a crafted invalid signature under a maliciously generated verification key, if the AVX2 implementation is used.

## Mitigation From version `0.0.9` the edge case is handled correctly and invalid signatures are rejected.
