Update tutorial (#72)

* Change title (ISD-2259)

Move away from titles like "Quick guide"/"Getting started" and toward a common convention of "Deploy X charm for the first time"

* Prerequisites --> Requirements (ISD-2266)

* Update headers, add a setup section (ISD-2268)

* Update check command, add cleanup section (ISD-2281)

* Update names of the listeners to align with pass-app-charmer
