Clarify `raw_path` Definition for WebSockets Protocol in the Specification

[raptium]

The definition of raw_path in the ASGI specification differs slightly between HTTP and WebSockets protocols.

• HTTP: The specification explicitly states that the query string is excluded from raw_path.

https://github.com/django/asgiref/blob/b7aaa795fbbea7ca88458279cf8302533d249101/specs/www.rst?#L107-L110

• WebSockets: The specification does not mention whether the query string should be included or excluded from raw_path.

https://github.com/django/asgiref/blob/b7aaa795fbbea7ca88458279cf8302533d249101/specs/www.rst?#L318-L321

To ensure clarity and consistency, it would be beneficial to explicitly define the behavior of raw_path for WebSockets:

1. If the query string should be excluded: The specification should use the same wording as in the HTTP section to avoid ambiguity.
2. If the query string should be included: This should be explicitly stated, along with any rationale for the differing behavior.

Given the potential for confusion, it would be helpful to clarify this in the specification.

Yeah, having this difference looks a bit weird. Do you remember if it was intentional? @andrewgodwin

I do not believe that was intentional - my guess is that we specifically clarified it for standard HTTP but not for WebSocket. I would say we should update the WebSocket side to say that it also excludes the query string.
