Percona Helm Chart for PSMDB-DB is missing the crVersion field

Background
The crVersion field should reside in the PSMDB Manifest.
Currently, the template does not contain this field.
the field is used by the PSMDB Operator, for example here
and many more cases.
I myself got to the issue since the isEncryptionEnabled function was not behaving as expected

ToDo

  • add crVersion field to the cluster.yaml Spec
  • update Chart.yaml version to version: 1.12.5
  • add default value in values file crVersion: 1.12.0
  • update README

I’ve added a PR on this : https://github.com/percona/percona-helm-charts/pull/169
