help: switch from formatter module to textwrap

Since Python has deprecated the formatter module, switch to the textwrap
module instead for reflowing text.  We weren't really using any other
feature anyways.

Verified by diffing the output before & after the change and making sure
it was the same.

Then made a few tweaks to tighten up the output.
