RPC: Add comment about eth_protocolVersion expectations
While looking at the RPC `eth_protocolVersion` to see exactly what it should
report when there are multiple `eth/NN` versions supported by a node, I found
some differences in the documentation:

- The old Ethereum wiki documents it as returning a decimal string.

- But Infura documents it as returning 0x-prefixed hex string.

- Geth 1.10.0 has removed this call entirely "as it makes no sense".
