Remove stray top-level require 'pry'

Leftover debugging require, not used by any binding.pry call site in
the gem — broke on any consumer that doesn't bundle pry itself
(mozo-backend's production environment, which excludes the
development/test group pry lives in). Caught deploying mozo-backend
against this gem for the first time via its new gitea git source.
