docs: updates outmoded steps from apps links

[lukegalbraithrussell]

Summary

None of these were 404'ing, as we have redirects, but they are noise for our internal check for broken links.

Removed some reference sentences as steps from apps api pages do not exist anymore, they redirect to the changelog entry
