"zks_getBytecodeByHash" method shouldn't accept txn hash input

[sarahschwartz]

In get_bytecode_by_hash at https://github.com/matter-labs/alloy-zksync/blob/main/src/provider/mod.rs#L206 a txn hash is passed in zks_getBytecodeByHash, but this method is meant to accept the bytecode hash of a contract, not a transaction.

It looks like it's just a typo -- both transaction and bytecode hashes are 32-byte, so while the doc-comment and parameter naming are incorrect, the method should work as intended.
So, while it certainly should be fixed, it's not technically a bug.
