helm: Do not recommend setting values.yaml
The `values-ha.yaml` recommends setting `-f values.yaml`. This
should not be used, as it will encode defaults (like the container
image versions) in the stored helm state so that upgrades will
preserve these versions by default.
# This values.yaml file contains the values needed to enable HA mode.
# Usage:
-# helm install -f values.yaml -f values-ha.yaml
+# helm install -f values-ha.yaml
# -- Create PodDisruptionBudget resources for each control plane workload
enablePodDisruptionBudget: true
