Heading text should be before the word required

[GeorgeKerscher]

When you navigate the fundamental test book by heading to go to the next test, it says required and it should say the text of the heading, i.e. the test.

The new books have been added without this "required"/"optional" text, since it was a relic from the mainstream testing. I think that long-term, we'll do the same with all the accessibility testing books.
