week 3 feedback - Githubissues

Overview of changes

Update to `.mdx` files and add buttons for navigating between lessons
tweaked some phrasing/grammar throughout the lesson material and assignment
wrapped code in tagged code fences (eg: " ```js") or <code> blocks as needed for correct highlighting

Material changes

Nothing urgent; I reworded some things and added a couple links but I didn't find any bugs or issues that need to be brought into the Wordpress version with any haste. Nor did I add any significant bits of content for this week's lesson.
