Broken links: missing the language in the url

reported on slack

A lot of the documentation links from docs.apify.com seem broken
API -> Client for JavaScript -> Get Started -> goes to https://docs.apify.com/api/client/docs -> shows up as not found
API -> Client for Python -> Get Started -> goes to https://docs.apify.com/api/client/docs/overview/introduction -> shows up as not found
SDK -> SDK for JavaScript -> Get Started -> goes to https://docs.apify.com/sdk/docs/guides/apify-platform -> shows up as not found
SDK -> SDK for Python -> Get Started -> goes to https://docs.apify.com/sdk/docs/overview/introduction -> shows up as not found
CLI -> Learn More -> goes to https://docs.apify.com/docs -> shows up as not found

It works when languages is added, e.g.
❌ https://docs.apify.com/api/client/docs
✅ https://docs.apify.com/api/client/js/docs
