Support for ValueTuple type in response body type

See original GitHub issue

Describe

Tuple and ValueTuple seem to have the same response. However, when ValueTuple type is used for Description, “Example” (or Schema) is not described normally.

For example, I wrote the code like this, (check body Type). Then I check the response && swagger.

code

[Function(nameof(PetStoreHttpTrigger.SystemTupleHandler))]
[OpenApiOperation(operationId: "SystemTupleHandler", tags: new[] { "tuple" })]
[OpenApiResponseWithBody(statusCode: HttpStatusCode.OK, contentType: "application/json", bodyType: typeof(Tuple<int,double,string>))]
public async Task<Tuple<int,double,string>> SystemTupleHandler(
   [HttpTrigger(AuthorizationLevel.Function, "GET", Route = "system-tuple")] HttpRequestData req,
   FunctionContext executionContext)
{
    var tuple = Tuple.Create(1,1.5,"3");
    return await Task.FromResult(tuple).ConfigureAwait(false);
}

[Function(nameof(PetStoreHttpTrigger.SystemValueTupleHandler))]
[OpenApiOperation(operationId: "SystemValueTupleHandler", tags: new[] { "tuple" })]
[OpenApiResponseWithBody(statusCode: HttpStatusCode.OK, contentType: "application/json", bodyType: typeof(ValueTuple<int, double, string>))]
public async Task<ValueTuple<int, double, string>> SystemValueTupleHandler(
   [HttpTrigger(AuthorizationLevel.Function, "GET", Route = "system-valuetuple")] HttpRequestData req,
   FunctionContext executionContext)
{
    var tuple = ValueTuple.Create(1, 1.5, "3");
    return await Task.FromResult(tuple).ConfigureAwait(false);
}

[Function(nameof(PetStoreHttpTrigger.SystemValueTupleSyntaxHandler))]
[OpenApiOperation(operationId: "SystemValueTupleSyntaxHandler", tags: new[] { "tuple" })]
[OpenApiResponseWithBody(statusCode: HttpStatusCode.OK, contentType: "application/json", bodyType: typeof((int,double,string)))]
public async Task<(int,double,string)> SystemValueTupleSyntaxHandler(
  [HttpTrigger(AuthorizationLevel.Function, "GET", Route = "system-valuetuplesyntax")] HttpRequestData req,
  FunctionContext executionContext)
{
    var tuple = (1, 1.5, "3");
    return await Task.FromResult(tuple).ConfigureAwait(false);
}
