Investigate and look into better outbound link tracking for articles+

Related to #2114 , but Articles+ does a little bit different stuff with outbound links. Mentioned by @jkeck in standup on 11/9

See d4ec5ed69a7c69506312912e8716482012c7d75c for when this was added.

We have an internal action that calls a fetch on the article search service (equivalent to going to the record view) where the eds_fulltext_links field is available in the returned document.
