[Task] Re-Check cargo audit after protobuf fix

## Description
Re-check if we still need to ignore RUSTSEC-2024-0437 in `cargo audit` or if we can bump deps and remove it after https://github.com/iotaledger/iota/pull/6292 has resolved https://github.com/iotaledger/iota/issues/5861.

Start by running cargo audit and inspect the dependency configuration for the RUSTSEC-2024-0437 ignore. Check whether the protobuf fix in PR 6292 resolved issue 5861; done means confirming the audit result and either retaining the ignore or removing it after a dependency bump.
