Docs: improve rendering for lists

[bmicklea]

Describe the problem you're trying to solve
Bulleted and numbered lists in the docs are a little hard to read - they're not very indented and generally just kind of run together with the other text. See the use-cases.md as a good example.

Describe the solution you'd like
A little deeper indent on lists would help. Perhaps if there was more space between regular paragraphs and a little less at the top of the first item in a list that would help too. The docs need room to breathe! 😄

Describe alternatives you've considered
Not using lists, but that seems extreme.

Additional context

We'll add a larger line spacing and a deeper indent. We'll also color the bullet points and numbered lists.
