Fix formatting in all the courses

[jaykerbelis]

Example:

• Url's should be clickable
• If you want monospace to use the backtick format
• Make sure that text doesn't go off the side of the screen
• Instead of italics, consider using Hints that theme-hope provides
• Add figures and descriptions to the deployment guide images
• Retake figure to make sure that text is clear in the screen captures
