Investigate why Python SDK submenu link returns 404

[TC-MO]

Bug

The Python SDK docs submenu links to a broken URL that returns HTTP 404.

Steps to reproduce

1. Go to https://docs.apify.com/
2. Select SDK for Python
3. Click Docs in the submenu (even though it appears active)

Expected behavior

The Docs link navigates to a valid page.

Actual behavior

• Main menu correctly links to: https://docs.apify.com/sdk/python/docs/overview
• Submenu incorrectly links to: https://docs.apify.com/sdk/python/docs/introduction → 404

On reload, the broken URL redirects to:
https://apify.github.io/apify-sdk-python/docs/introduction/#__docusaurus_skipToContent_fallback
which is also broken (Page Not Found).
