Follow-up from "Resolve "Add new documentation and link for automating Visual Review feedback""

Overview

The following discussion from !14789 (merged) should be addressed:

• @pslaughter started a discussion:

  issue: Is there anyway we can get this URL from the BE (here's an example)? Some customers (especially EE ones) are behind a closed network and we should link them to the help on their instance, not docs.gitlab.com.

  I see we have other hardcoded paths to docs.gitlab.com. I'm fine if we want to create a follow up issue for this 🤷, but it'd be nice to fix it here 😄.

Problem to solve

As a user on an airgapped network, I want documentation for usability features to be available to me, so I can troubleshoot and use those features.

Proposal

Change the hardcoded docs.gitlab.com link to a URL we get from the BE so customers on airgapped networks can see the documentation.
