Jsonrprsee Notification Spec

[aniketfuryrocks]

Hi, I was working on porting the pubsub tests of solana from jsonrpc to jsonrpsee. I noticed that the tests expect the "jsonrpc": 2.0 field to be there while the new jsonrpsee crate doesn't return it in the response. Is this valid jsonrpc ?

This works

#1045,

The "jsonrpc" field can be omitted but it's an Option so should be possible enable.
Perhaps it was changed unintentionally would be better to send out notifications with the jsonrpc field by default.

Can you open an issue and write how to reproduce it?
