Add Descope Shell Plugin

[scottisloud]

Overview

This PR adds a shell plugin for Descope (https://www.descope.com). Currently it supports the authentication of an admin using a Project ID and Management Key.

I am not a Descope user, so the nuances of that service are not well known to me. This may need to be reverted to draft if the main value lies in non-Descope admin CLI users. If that's the case I'll have to add functionality to handle Access Keys as well.
