Installation Failing with Error #310

$ helm install my-release concourse/concourse Error: unable to build kubernetes objects from release manifest: unable to recognize "": no matches for kind "PodDisruptionBudget" in version "policy/v1"

@abhishekpareek19 what's your k8s cluster version?

Seeing this on a k8s cluster running v1.19.9. Doing a bit of research and found this info:

pdb stands for PodDisruptionBudget. Kubernetes API introduced this resource in the initial release of version 1.0. The API remained fairly stable until version 1.21, when it was graduated and promoted to policy/v1 from policy/v1beta1. policy/v1beta1 is currently deprecated, and will be removed in version 1.25.

worker-policy.yaml in this chart specifies the following:

apiVersion: policy/v1
kind: PodDisruptionBudget

Seems it's presuming a cluster version >= 1.21 is being used.

Above is true for PDBs (https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.21/#poddisruptionbudget-v1-policy) but not for PodSecurityPolicies changed in https://github.com/concourse/concourse-chart/commit/ade9143b9c3d4c427fd9ddc71f7a3db377f4cdf1. See https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.21/#podsecuritypolicy-v1beta1-policy - there is no podsecuritypolicy in policy/v1.

I think this needs to be reverted.
