Linking in markdown

Turns out a lot of the find and replacing to include the baseurl in markdown links broke them.

`{{< ref "kbtopic/chaoss-groups/" >}}` is likely a better syntax that seems to be seen by markdown correctly

No file or test is named in the issue. Start by locating the find-and-replace logic that adds the base URL to Markdown links, then check how the shown ref syntax is processed. Done means links render correctly without being broken by base URL handling.
