Consider grouping all PIN related policies in a group.

To be consistent (at least with the recently added policies) please rename this
one to PinUnlockWeakPinsAllowed.

Also in this case the True value should mean weak pins are allowed and False
that they are not. Your documentation currently states the opposite.
