Public action `verifyHash` does not work with zksync public client

Viem Version

2.16.5

Current Behavior

When doing anything that uses verifyHash internally (like verifySiweMessage) if the public client in context is a zksync client verification fails. Reason for that is verifyHash uses erc-6492 for signature verification and has a constant called universalSignatureValidatorByteCode but regular bytecodes does not work on zksync so verification fails even when the signature is valid. This is not a problem for eoa's (you can just verify with an arbitrary public client) but it is breaking for smart contract accounts

Expected Behavior

Either a different constant bytecode should be used when the chain in context is zksync or 6492 flow should not be used and verification flow should revert to old flow (1271 + ecrecover).

Unfortunately, zkSync handles contract deployments a bit differently to Ethereum, so using different bytecode / deployless verification probably won't work. :\

Can see what I can do.

Added a fallback for this scenario here: https://github.com/wevm/viem/commit/ec3b0e08f0a379249224e65092277191f1a8502b.
