graphql-ws integration adjustments and tests (V3)

[enisdenjo]

Closes #1513

• Fix "should execute mutation" test which is failing because the usePreventMutationViaGET plugin is preventing mutations from running over GETs and the WebSocket upgrade request is a GET.

  I was considering checking the headers and skipping the check if Upgrade: websocket; however, the request in the context is a Node request... @ardatan suggestions? Use normalizeNodeRequest from @whatwg-node/server? Include socket in context and skip check if socket is set (this would require WebSocket type)?

  P.S. the test is not failing on v3-graphql-http branch because I dropped the plugin and left the check to graphql-http.

Maybe this fix can work

Fixed with https://github.com/dotansimha/graphql-yoga/tree/fix-graphql-ws-compat.

Made me think, maybe we should implement WebSockets over Fetch API? There's nothing out there for it yet the Fetch Standard has a section for WebSockets. 🤔

@enisdenjo You are right. There is only WebSocket API but I am not sure it is enough for server implementations.
