journeys index: link 'Apprenticeship Patterns' to the O'Reilly book

The /journeys hero copy attributes inspiration to Apprenticeship
Patterns; wraps the phrase in an outbound link so readers can find
the book.

  https://www.oreilly.com/library/view/apprenticeship-patterns/9780596806842/

Uses .text-link styling (the same accent-underline pattern that
the rest of the site uses for outbound text links). No new chrome,
no new CSS.
