feat(openapi): a fresh coat of paint on openapi inspect (#1127)

## 🧰 Changes

The biggest problem I've had since originally building our `openapi
inspect` command has been that the tables between OpenAPI and ReadMe
features aren't of consistent widths. Drives me up a damn wall.

So I'm giving a fresh coat of paint to this command that deserves some
love.

* [x] Consistent table widths. <sub>existential grumbling</sub>
* [x] Table headers are now yellow instead of green to reduce the amount
of color thrashing we have going on.
* [x] URLs to OpenAPI spec definitions our own docs are now dimmed
instead of grey.
* [x] Tossed an emoji on the different feature sections. 🌲 for OpenAPI
and 📖 for us.
* [x] Swapped out the ✅ emoji for used features in place of 🟢 and 🔴
circles.
* [x] Usage strings like "2 Media Types", "a total of 9 Operations", or
"a single Security Type" are now lowercased because it looked funky as
hell.
* [x] Bumped OpenAPI spec links to the latest versions for 3.0 and 3.1.

I also made a couple minor readability to how we construct this table
because the code was a bit gnar with some deeply nested `array.push()`
calls.

## 🧬 QA & Testing

This is what it all looks like:
