rpc: check that "version" is "2.0" in request objects (#25570)

Browse Source 
The JSON-RPC spec requires the "version" field to be exactly "2.0",
so we should verify that. This change is not backwards-compatible with
sloppy client implementations, but I decided to go ahead with it anyway
because the failure will be caught via the returned error.
