Describe your suggestion

Since the Testing Section contains upcoming lessons (according to this Discord message) I'll take this chance to address all markdown lint issues in the section.

There are two lessons with issues:

• Model Testing
• Unit Testing

Both lessons' files have similar problems - TOP004, MD009, MD040 etc...
