Add support for passing extra command-line args via Helm values (#2892)

* Add support for passing extra command-line args to the operator via Helm values

This change introduces the ability to specify additional command-line arguments for the Postgres Operator via the "extraArgs" field in values.yaml. Documentation has been updated with details on new arguments "-kubeqps" and "-kubeburst" added before: https://github.com/zalando/postgres-operator/pull/2667. The chart version is bumped to 1.14.1 to reflect these changes.

* reverted charts/postgres-operator/Chart.yaml
