Issue description: 

In https://role.rhu.redhat.com/rol-rhu/app/courses/rh294-9.0/pages/ch10s02, there's a step that says:

"It must contain one play that runs on managed hosts in the dev group. Its play must use one task to add the users joe and sam to all managed hosts in the dev group."

I found this confusing between host groups and actual groups that users can be added to on RHEL. I would suggest clarifying this as host groups, since I created a dev user group on the systems and added the users to that, which is a common activity when managing users.

Looking through the solution clarified that this meant host groups.
