Issue:
[v1.15] Add chat configuration to index settings
**Description**
Each index that you want to be searchable through chat needs specific configuration

**Basic example**

https://www.meilisearch.com/docs/guides/ai/getting_started_with_chat#configure-your-indexes-for-chat

```bash
curl \
  -X PATCH 'http://localhost:7700/indexes/movies/settings' \
  -H 'Authorization: Bearer <master-key>' \
  -H 'Content-Type: application/json' \
  --data-binary '{
    "chat": {
      "description": "A comprehensive movie database containing titles, descriptions, genres, and release dates to help users find movies",
      "documentTemplate": "{% for field in fields %}{% if field.is_searchable and field.value != nil %}{{ field.name }}: {{ field.value }}\n{% endif %}{% endfor %}",
      "documentTemplateMaxBytes": 400,
      "searchParameters": {}
    }
  }'
```
