feat: Fixing docs vs actual product disprepancies

[mtrunkat]

I confronted the docs against the local Console. This fixes a wild mix of outdated URLs, outdated texts, buttons, and other.

Go over all pages in https://docs.apify.com/platform documentation, i.e., all subpages of
https://docs.apify.com/platform page. And check them against reality. Use local version of Apify
Console. Console is running at http://localhost:3000/ and credentials are mu :
a3 if needed. If you find any discrepancies between docs and actual UI and product note
them in a markdown document. Each page should have a section describing it's problems there and
also update the documentation source markdown files here in the repository to reflect that.
