JSON encoding of returnValue field in the EVM Logger #31196
Description
It was reported in NethermindEth/nethermind#8186 that in the EVM logger geth returns returnValue (the return data of the top call) as non-prefixed hex string. This seems wrong. It has been there forever and tooling depends on it I imagine so it is an unfortunate situation. At risk of angering people IMO we should add the hex prefix. It is not a big change for users.
