SpinButton: Fix an obviously wrong arg description

:climb-rate is not about what you get when you single-click on a button,
as this implied: it's what happens if you hold down a button or a key.
Fix the description of @climb_rate to new(), and while here, mention the
key in the blurb of :climb-rate itself.
