Description

### Describe the bug

I created a REST API using lambda annotations. The FromBody works like charm, but I found that FromQuery annotation didn't work like expected. It gives me null value instead of object.

### Expected Behavior

FromQuery should works like FromBody

### Current Behavior

It doesn't work.

### Reproduction Steps

I created a lambda function like below.
```csharp
public class TestQueryParamsDto
{
public string x { get; set; } = "hello";
public string y { get; set; }
}

[LambdaFunction(ResourceName = "TestQueryParams", Policies = "AdministratorAccess")]
[RestApi(LambdaHttpMethod.Get, "/api/test-query-params")]
public APIGatewayProxyResponse TestQueryParams(APIGatewayProxyRequest request, [FromQuery] TestQueryParamsDto query)
{
var response = new APIGatewayProxyResponse();

response.StatusCode = 200;
response.Body = JsonSerializer.Serialize(new
{
message = "OK",
request = request,
query = query
});

return response;
}
```
After I test it in lambda-test-tool, I get the query argument unexpectedly has null value instead of object. Same thing happen to published functions.

Sample function input for lambda test tool:
```
