fix(neutron): revert OpenStack Helm chart version

https://review.opendev.org/c/openstack/openstack-helm/+/949058 contained
an invalid volumes spec for the neutron-ironic-agent preventing it from
starting up. So revert back to before that landed.
https://review.opendev.org/c/openstack/openstack-helm/+/952611 has been
submitted to fix this.
