Ed Page 9b23a09f7a fix(help): Don't rely on ALL CAPS for headers
I see them fulfilling two roles
- A form of bolding
- As a callback to their placeholder in usage

However, it is a bit of an unpolished look and no other CLI seems to do
it.  This looks a bit more proefessional.  We have colored help for
formatting and I think the sections relation to usage will be clear
enough.
