zksync strikes back!

Community https://community.brave.com/t/zksync-era-failed-transactions-due-to-eip-1559-error

It appears that zksync Era has finally implemented the eth_feeHistory RPC, absence of which previously broke EIP-1559 fee estimation (#30473), but the response breaks our parser. As a result, users are unable to transact on zksync anymore. See an example from syncswap below.

On the bright side, getting fee estimates is now 2x faster on zksync.
