usePrepareTransactionRequest fails eth_maxPriorityFeePerGas rpc call on MetaMask injected connector

[holic]

Describe the bug

I am using usePrepareTransactionRequest, which internally calls eth_maxPriorityFeePerGas using the connector client, which fails on injected MetaMask connector:

{
    "code": -32601,
    "message": "The method \"eth_maxPriorityFeePerGas\" does not exist / is not available.",
    "data": {
        "origin": "http://localhost:5173",
        "cause": null
    }
}

I worked around this for now with:

const fees = useEstimateFeesPerGas({ chainId });
const prepared = usePrepareTransactionRequest({
  chainId,
  to,
  value,
  maxPriorityFeePerGas: fees.data?.maxPriorityFeePerGas,
});

I think we can resolve this by not using the connector client for usePrepareTransactionRequest. It's not needed.
