Second hop towards 1.11.2. 1.9 stops serving longhorn.io/v1beta1 (nothing
in this repo uses it) and renames orphan-auto-deletion (false here) to
orphan-resource-auto-deletion during the upgrade. Chart values are
unchanged from 1.8.2.
Checked beforehand: 17 healthy volumes plus 2 detached, no backing
images, every Longhorn CRD already stores only v1beta2, and system backup
pre-upgrade-v1-8-2-202610221408 is Ready.
