fix: just check for the base api version.

`helm template` uses the `chartutil.DefaultCapabilities` in the `.Capabilities.APIVersions` check. This is limited to the Kubernetes group/version and omits the kind. For the purpose of making the sure the PDB is being installed with the correct policy version, just checking if `policy/v1` exists in the cluster should be enough.
