docs: redirect SDK JS versions page to changelog (#1714)

Redirects the traffic from `/sdk/js/versions` to
`/sdk/js/docs/changelog`

Connected to apify/apify-sdk-js#416

Alternatively, we don't have to merge this (to keep the `nginx` conf
clean), the `versions` page had likely 0 traffic (only linked from the
sitemap).
