Guide Cards CTA Label

Short Description:
Change the CTA label so it's less descriptive and accommodates future content structure changes. For example, currently if chapters are changed to module, the CTA needs to change also. Perhaps change it to Learn more, Read more, etc.

User Story: TBD
Acceptance Criteria: TBD

Start by locating the guide cards and the current CTA label in the JavaScript frontend. Choose a label that does not depend on whether content is called chapters or modules, then verify the updated CTA appears consistently on guide cards.
