Implement media in prompt

What about the text-to-image support? Google should have support for that with Imagen 2 & 3. But should it be a different ticket?

@jibla is this duplicate of https://www.drupal.org/project/gemini_provider/issues/3493942 🐛 Problems generating alt text from uploaded images Active ?
then we can close this as duplicate

or is it about what @merilainen mentioned text to image model - not available at this moment ...
then add more info and postpone ... till gemini provides the model api ...

I need to check if we need to do more here.
