Add latest GPT models

I wonder if its worth instead extending OpenAI module; it automatically gets the latest models because it uses the API to retrieve available models. We could use it's Service instead of doing a custom integration like is currently being done. Otherwise we will endlessly have to keep upgrading this module right?

Different model versions give different results, I can't explain why. For now it's preferrable to use gpt-4-0125-preview, but maybe new models will be better soon.

If we extend openai module you can choose for yourself which model, no problem. There is a configuration page that then appears.

We have now ✨ Use the AI module under the hood Active to make this issue redundent.

Latest models all available in https://www.drupal.org/project/ai_tmgmt → . Thanks for your patience!
