feat: use zks_estimateFee for getting EIP 1559 price params on zkSync chains

[tkporter]

Description

Uses zks_estimateFee (https://docs.zksync.io/zksync-protocol/api/zks-rpc#zks_estimatefee), following the pattern that is used in the JS/TS zkSync tooling:

sendTransaction calls populateFeeData https://github.com/zksync-sdk/zksync-ethers/blob/64763688d1bb5cee4a4c220c3841b803c74b0d05/src/signer.ts#L650

populateFeeData calls estimateFee https://github.com/zksync-sdk/zksync-ethers/blob/64763688d1bb5cee4a4c220c3841b803c74b0d05/src/signer.ts#L702

estimateFee uses that json rpc https://github.com/zksync-sdk/zksync-ethers/blob/main/src/provider.ts#L311
