Support "application/graphql+json" media type in GraphQL HTTP mapping

As seen in spring-projects/spring-graphql#108, the GraphQL HTTP spec now
requires the "application/graphql+json" media type and accepts
"application/json" for backwards compatibility.

This commit updates the `RouterFunction` definition for the GraphQL HTTP
endpoints so that both types are accepted.

Closes gh-30407
