Keep onboarding's new introduction honest about computers

#861 turned onboarding into a looping introduction whose computer scene is
labelled "Each Bot has its own computer". Label and heading now say what
every Bot gets, and the check reads the route's words, since the looping
scene cannot be reached under happy-dom.
