Long success messages can break mid-word

Long success messages can break mid-word, like this example from Chapter 4, section 11:

Great job! In this case study, you will evaluate this model, plus two kinds of gradient boosting models.

I think one well-placed call to stringr::str_wrap would fix them all (and preserve the emoji's, hopefully), but can't find where to place it, or how to test it.

Yep, I noticed this as well and hadn't found a way to address it yet.

• The success messages are all in individual files called test_02_11_2.R and similar, and are here in the repo.
• The test files get used in this component that generates the code exercises.
