test: Increase sleep tolerance in request_max_duration test for Windows CI (#1827)

## Summary

- Increase `asyncio.sleep` from 50ms to 200ms and tolerance from 15ms to
50ms in `test_request_max_duration_tracks_maximum` to fix flaky failures
on Windows CI where timer resolution is ~15ms.

## Context

- [Failed
run](https://github.com/apify/crawlee-python/actions/runs/23786266607/job/69310149225?pr=1823)
— `asyncio.sleep(0.05)` only slept ~34ms on Windows, falling below the
`0.035s` threshold.
