fix: update SDK JS URLs after docs restructure (apify-sdk-js#542, #562) (#2280)

The SDK JS docs reorganization renamed paths from guides/apify-platform
to numbered directories. Update Nginx rewrites and CI test URLs to
match.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk: only adjusts Nginx rewrite targets and CI header-check URLs;
impact is limited to routing/redirect behavior for SDK JS docs paths.
> 
> **Overview**
> Updates SDK JS documentation routing after the docs restructure.
> 
> `nginx.conf` rewrites for `/sdk/js/docs` and legacy guide URLs now
redirect to the new `overview` pages (including `next`), replacing
redirects that previously pointed at `guides/apify-platform`. The GitHub
Actions Nginx header assertions are updated to hit the new JS SDK docs
path (`/sdk/js/docs/introduction/quick-start`) instead of the old guide
URL.
