fix icebox migration
The second job here would have never ran: the first job would have repeatedly warned about stale tickets, constantly reseting the timer.
By using the (newly created) Stale label, we ensure that
-
the first job doesn't constantly reset the timer (which would have been really annoying)
-
that the second job can actually run
This implies reducing the interval on the second job, because it starts counting after the first one has run.
This also implies that, to reset the first timer, the Stale
label
needs to be removed, which the bot now does as well, if a ~"Needs
Information" ticket gets updated.
(Note that we may want to generalize this to other labels or all labels, but for now we're keeping the scope limited to ~"Needs information".)
