Docs Mismatch: response_format dictionary syntax conflicting with types.GenerateContentConfig

#### Description
There is a syntax conflict in the official structured output documentation. The Python code blocks on the [Structured outputs](https://ai.google.dev/gemini-api/docs/structured-output) documentation page use a deeply nested raw dictionary structure for configuring JSON schemas.

```python
config={
"response_format": {"text": {"mime_type": "application/json", "schema": Recipe.model_json_schema()}},
}
```

However, the modern `google-genai` Python SDK recommends and implements structured generation using flat, top-level keys within `types.GenerateContentConfig` (or equivalent dictionary mapping):

Example:
```python
config={
response_mime_type="application/json",
response_schema=Recipe
}
```

#### Environment details

- Programming language: Python
- OS: linux-mint
- Language runtime version: 3.12.3
- Package version: 2.6.0

#### Steps to reproduce

1. Navigate to the documentation at: https://ai.google.dev/gemini-api/docs/structured-output

2. Observe the Python tabs under the "Recipe Extractor", "Streaming", and "Structured outputs with tools" sections.

3. They all use the nested `"response_format"` dictionary configuration instead of the native SDK schema parameters.

Making sure to follow these steps will guarantee the quickest resolution possible.

Thanks!
