Add gpt-image-1 image to image capabilitites

This is a duplicate of which issue?
Got a bit into trouble since last update from dev-1.1.x#f3c8cae
I had ImageToImage working with OpenAI, and then lost all models provided by OpenAI.

Sorry about that @dan - active again and I will move this to 1.2.x, since it will require AI 1.2.x.

Thanks @marcus, no problem. If it helps, here is the code that I added to this patch to make the ImageToImage working:

This looks good, it reviewed, but it can't be merged until the image-to-image issue is merged: ✨ Create Image-To-Image operation type Active .
