Right now, we're not specifying the version constraints
on RuboCop that is shipped when a new gem is created.
This can break specs which runs rubocop on a new
skeleton gem as the newer versions of RuboCop are
released.
This commit ensures that the specs don't break by
constraining the RuboCop version.
