It's ok, but please add a label rpcUrl to ethereum_steth_etherjs_request_total.

LGTM in general, but I have one request. If we're talking about generic metrics like ethereum_steth_network_errors_total we should be able to understand which service/vendor/API cause these errors. Hence, we need a sub-dimension here as a label with a name of remote party.
