Update generics on WebFlux RouterFunctions.Builder 

Consistently allow subtypes of ServerResponse to be returned for any
provided HandlerFunction and HandlerFilterFunction. Both allow use of
subtypes such as EntityServerResponse and RenderingResponse, and
in the end we support any ServerResponse.

Closes gh-35791
