fix(academy): use export_data() with keyword arguments (#2171)

Enabled by apify/crawlee-python#1597
Fixes #2112

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Switches Python Crawlee examples to the unified
`crawler.export_data()` API in the Academy lessons, replacing deprecated
`export_data_json`/`export_data_csv` calls while preserving parameters.
> 
> - In `12_framework.md`, update export examples (including logging and
exercise solutions) to `await crawler.export_data(path='dataset.json',
ensure_ascii=False, indent=2)` and `await
crawler.export_data(path='dataset.csv')`
> - In `13_platform.md`, update export calls in the platform lesson to
the same `export_data()` usage
>

 After running the scraper again, there should be two new files in your directory, `dataset.json` and `dataset.csv`, containing all the data. If we peek into the JSON file, it should have indentation.
