Describe the bug
OpenAI API fails with error if generic type is used for ResponseFormat:

HTTP 400 (invalid_request_error: invalid_value)
Parameter: response_format.json_schema.name

Invalid 'response_format.json_schema.name': string does not match pattern. Expected a string that matches the pattern '^[a-zA-Z0-9_-]+$'.

To Reproduce
Use any generic type as ResponseFormat. For example:

public class Cart<T>
{
   public decimal Total { get; set; }
   public List<T> LineItems { get; set; }
}

public class LineItem 
{
   public class ProductName { get; set; }
   public int Quantity { get; set; }
}

Expected behavior
This issue is caused by use of GetType().Name at
