Add support for paragraphs in translations

Needed this also, I've worked a little bit more on the previous patch, with the following changes:
- For some situations where paragraphs were translated, all existing translations were overwritten, should now be fixed
- Changed how the calls to chatgpt are made, instead of 1 big call (which resulted in a lot of tokens being used + keys being overwritten) the values are now being loaded separately
- Kept all existing paragraph fields instead of only the translatable ones

Probably needs some more refining and cleaning up.

ideally this issue (patch) also ends up in https://www.drupal.org/project/ai/issues/3457200 ✨ ai_translate submodule Needs work

I tried to add a batch to it. This way you can see a progress bar.

Fixes latest patch.

This patch supports a batch.
Also the input field for the api key needed to be longer. This patch also handels that issue.

It works in the ai module and I think most people will (and even should) switch to that one.
Anup can help with the maintenance there, then we dont need to maintain duplicate modules (and the AI module has more functionalities).
For me this may be closed (outdated).
