Add x.ai (Grok) as AI provider for Zammad 7.0

Title: Add x.ai (Grok) as AI provider for Zammad 7.0

It would be great if you support x.ai from the start of Zammad 7.0.

Edit: Just saw this Github issue. This would resolve the problem, because the x.ai API is OpenAI compatible: AI Provider - Add support for OpenAI-compatible servers · Issue #5864 · zammad/zammad · GitHub

Doesn’t Grok provides an OpenAI-compatible API?

Edit: According to their website, they do.

Yes, as I wrote in my edit, it is compatible. When Issue 5864 is implemented, it can be used.
