Fundamentals Part 1: Update list items to layout styling guide

[Churtified]

Because

There are many lessons that have inconsistent styling techniques. By correcting the list items to a unified method, this makes all markdown documents consistent, easier to read, and edit in the future.

This PR

• Updated all unordered list items from asterisks to the recommended hyphen.
• Updates all ordered list items from incrementing numbers to lazy numbering format.

Thanks for making the update and also resolving some of the lint errors! Would you want to resolve some of the remaining ones (blanks lines around headings, using asterisk syntax for strong/emphasis instead of underline)?

Also can you just update your comment from Closes [issue number] to Related to [issue number], we don't want this PR automatically closing the issue since it's tied to several lessons.

Thanks, I was confused at the markdown lint. But now I understand what it is! I have made all the changes and changed to Related to [issue number]. Appreciate the feedback.

Understandable! It's a new addition to the repo to help automate the process of finding these issues (rather than having to manually sift through lessons and find what needs to be updated). Thanks again for making these updates!
