.Net: Bug: The content type `application/graphql-response+json` is not supported.

[ian-work-1]

Describe the bug
When using ImportPluginFromOpenApiAsync() with data-api-builder and graphql and gpt-4 host6ed on azure the orchestrator throws the error 'The content type application/graphql-response+json is not supported.' when receiving the response.

To Reproduce
Steps to reproduce the behavior:

1. Setup a new agent that uses AddAzureOpenAIChatCompletion() and 'gpt-4', example repo here: https://github.com/tommasodotNET/chat-with-database
2. Setup graphql endpoint using https://github.com/Azure/data-api-builder/
3. Make a tool call to the OpenApi function

Expected behavior
The orchestrator should correctly parse the response from graphql.

*Env
deploymentName: "gpt-4",
C#
Windows
Visual Studio

Can be reproduced in this repo: https://github.com/tommasodotNET/chat-with-database

Not sure if it helps, managed to resolve the issue with this code:

_agent.Kernel.ImportPluginFromOpenApiAsync(
    pluginName: "dab_post", 
    filePath: Path.Combine(_promptPath, "dab.yaml"), 
    executionParameters: new OpenApiFunctionExecutionParameters()
    {
        ServerUrlOverride = new Uri(dabUrl),
        EnableDynamicPayload = true,
        IgnoreNonCompliantErrors = true,
        EnablePayloadNamespacing = true,
        HttpClient = httpClient,
        HttpResponseContentReader = ReadHttpResponseContentAsync
    }).GetAwaiter().GetResult();

 private static async Task<object?> ReadHttpResponseContentAsync(HttpResponseContentReaderContext context, CancellationToken cancellationToken)
 {
     // Read the content as string for both GraphQL and JSON responses
     if (context.Response.Content.Headers.ContentType?.MediaType == "application/graphql-response+json" ||
         context.Response.Content.Headers.ContentType?.MediaType == "application/json")
     {
         var content = await context.Response.Content.ReadAsStringAsync(cancellationToken);

         // Log for debugging
         Debug.WriteLine($"GraphQL response: {content}");

         // Parse and return as a JSON object
         return System.Text.Json.JsonDocument.Parse(content).RootElement;
     }

     // HTTP request and response properties can be used to determine how to read the content.  
     if (context.Request.Headers.Contains("x-stream"))
     {
         return await context.Response.Content.ReadAsStreamAsync(cancellationToken);
     }

     // Return null to indicate that any other HTTP content not handled above should be read by the default reader.  
     return null;
 }
