Deadlink: How it works Topics

Some of the topics and work pages link out to the "how it works Topics" page but that seems to no longer be available: https://help.openalex.org/how-it-works/topics

Seems like maybe these links should be replaced with this doc: https://docs.google.com/document/d/1bDopkhuGieQ4F8gGNj7sEc8WSE8mvLZS/edit#heading=h.5w2tb5fcg77r
