NewtonsoftJson support

[PapLabros]

Hi,

I have updated HotChocolate from 12 to 14 and I can't seem to find a way to force HotChocolate to use NewtonsoftJson instead of System.Text.Json for serializing the responses.

Previously I could do something like:

 /// <summary>
 /// The Hot Chocolate <see cref="DefaultHttpResultSerializer"/> the uses the NewtonsoftJson for serialization
 /// </summary>
 public class GraphQLNewtonsoftJsonHttpResultSerializer : DefaultHttpResultSerializer
 {
     /// <inheritdoc/>
     public override async ValueTask SerializeAsync(IExecutionResult result, Stream stream, CancellationToken cancellationToken)
     {
         // Initialize a JSON writer
         var writer = new JsonTextWriter(new StreamWriter(stream));

         // Write the raw JSON
         await writer.WriteRawAsync(JsonConvert.SerializeObject(result.ToResponseModel(), Formatting.None, NewtonsoftHelpers.Settings), cancellationToken);

         // Flush the text
         await writer.FlushAsync(cancellationToken);

         // Return
         return;
     }
 }

Is there a way to do something like similar?
