Is your feature request related to a problem? Please describe.

When installing the chart on K8s 1.21+, I receive the following minor warnings:

W1014 13:51:13.418999   62059 warnings.go:70] policy/v1beta1 PodDisruptionBudget is deprecated in v1.21+, unavailable in v1.25+; use policy/v1 PodDisruptionBudget
W1014 13:51:13.472216   62059 warnings.go:70] policy/v1beta1 PodDisruptionBudget is deprecated in v1.21+, unavailable in v1.25+; use policy/v1 PodDisruptionBudget

Also noticing that although in the opensearch-dashboards chart there is support for using Ingress.networking.k8s.io/v1, there is not in the opensearch chart which would be easy to add.

Describe the solution you'd like

Add support for using the policy/v1 and networking.k8s.io/v1 API versions.

Describe alternatives you've considered

N/A
