Better chunking/less text needed for content in "Conducting a rapid usability test"

In the "Conducting a rapid usability test" episode, the "Ensuring smooth data collection" section is a lot of text. Reducing this text and/or breaking it up would help it be more parsable. Below are some thoughts on how to achieve this, but other contributors might have different ideas. Keep in mind that a preferred teaching strategy is to use exercises to teach content, not just practice what was already written elsewhere.

Possible approaches:

- trim text
- make another section in the episode and move some content there
- move some content into callouts or collapsable divs

**Before addressing this issue,** please leave a comment describing your approach so that others can assist without duplicating work. Tag a reviewer (e.g. @jlcohoon) as well.
**Please check that the "Overview" and "Key Points" don't need adjusting after your edits**

Carpentries info on formatting the different kinds of callouts and collapsable content like exercises might be useful: https://carpentries.github.io/sandpaper-docs/instructor/component-guide.html

Start with the “Ensuring smooth data collection” section in the “Conducting a rapid usability test” episode and compare its structure with the Carpentries component and lesson-content guides linked in the issue. Propose the approach in a comment for review, then revise the section and check whether the episode’s “Overview” and “Key Points” still match the edited content.
