The version of the etcd chart the operator uses still contains the policy/v1beta1 version of the PodDisruptionBudget resource but this was deprecated in k8s 1.21 and removed in 1.25. This is important to prevent outages especially when using Karpenter which regularly replaces nodes and will happily remove all etcd pods at the same time without a PDB set.
