Stage list in generator is one off

This is minor, but it does kind of irritate me: pressing "1" at the stage list selects stage 0, pressing "2" selects stage 1, and so on.

I've considered adding an "index" parameter to the question for inquirer to address this, but I'm not sure it's the most elegant solution - even though it'd solve my problem, I don't feel it'd be best of problems in general, so I'm choosing to just suck it up as-is for now. (If I used inquirer more, and had more use cases, I might implement a more robust reconfiguration, such as letting list selection be keyed-in by value, or having arbitrary key-in values, or showing values, or showing numbered indices...)

Anyway, considering standard QWERTY keyboard number layout, this 1-indexing behavior is kind of most useful as-is, so... meh. Another reason I'm not really fighting this issue that much upstream.
