Is your feature request related to a problem?

Websocket messages can also be changed by size removing null entries.

The solution you'd like

As far as I saw, web socket payload message is converted into json string in GraphQLOverWebSocketProtocolHandler (namespace HotChocolate.AspNetCore.Subscriptions.Protocols.GraphQLOverWebSocket), formatter is private readonly JsonResultFormatter _formatter = new(); Can we change this formatter from dependency injection, it would be nice if we can ignore null values when sending message over websockets. Thx in advance
