The enterprise-wg and product-wg lists were deleted from the
openstack site per the announcement[*] on 2022-02-01, but I
neglected to push a change to remove them from our configuration
management, so Ansible helpfully recreated them for me. Clean this
up so I can re-remove the lists once and for all.
