POC supporting verbose descriptions for commands

Description and Context

I was poking around Stripe's CLI and noticed they support multiple descriptions for commands. A short one that shows when the command is listed a a child of another command, and a longer one when you run the help command for a specific command. Our equivalent would be hs --help vs. hs auth --help. For the former, it's nice to provide a concise description because the list of commands is long and it's hard to parse if each command has a wordy description. For the latter, it would be ideal to give the user more detailed information.

Unfortunately, yargs doesn't make this easy out of the box, but I think I found a pretty clean solution that would let us provide both a short and long description for commands. This POC shows what it could look like for the hs auth command.

The addVerboseDescribe is pretty straightforward. It checks to see if the user included the --help flag, grabs the original help output, and then logs out a new one. I tried to make it safer by allowing it to safely throw. If it throws, the help output will just fall back to the default yargs behavior, which is to log out the command's describe export.

Who to Notify

I don't love that we have to make the builders async for this to work, but I couldn't find a way to get around it. yargs.showHelp() is async and we need it to grab the original help output for the command.
