                Exposing HTTP/2 and HTTP/3 protocol error details from `SocketsHttpHandler`

    Exposing HTTP/2 and HTTP/3 protocol error details from SocketsHttpHandler
This proposal builds on the decisions made in our QUIC Exceptions Design proposal.
Proposed design

Define a new exception type ProtocolException, and embed it as HttpRequestException.InnerException
Throw ProtocolException directly from HttpResponse content read streams
In case of HTTP/3, embed QuicException as ProtocolException.InnerException
