community[minor]: Add tools calls to ChatEdenAI (#22320)

### Description  
Add tools implementation to `ChatEdenAI`:
- `bind_tools()`
- `with_structured_output()`

### Documentation 
Updated `docs/docs/integrations/chat/edenai.ipynb`

### Notes
We don´t support stream with tools as of yet. If stream is called with
tools we directly yield the whole message from `generate` (implemented
the same way as Anthropic did).
