Update ChatGpt to respect the default response key

Thanks for your finding Naveen.

Here's the patch to review

Hi Naveen,

I already pushed a fix for it: https://git.drupalcode.org/project/augmentor_chatgpt/-/commit/39eef82903...

We shouldn't send a new key "choices" in the output, we already have them inside the "default" key and we use them all or not depending if the user uses a "select" or "default" widget type.
