Suggestion - remove dev tools landing pages

[patrikbraborec]

Problem

The current landing pages for Apify dev tools (API, SDKs, CLI) are outdated and show information that is not very useful (like 130 GitHub stars).

Solution

Remove the landing pages and move users (developers) directly to the documentation for each dev tool. We might create an overview docs page, which is an industry standard.

Next steps

• Check analytics (mixpanel for user statistics of these pages)
