Wrong level of identation when supplying an imagePullSecrets

[jam-re]

When specifying a custom imagePullSecrets, the generated yaml is invalid due to the ident level specified in the template (should be 8 and is instead 2) :

Example :
https://github.com/openebs/cstor-operators/blob/v3.3.x/deploy/helm/charts/templates/cspc-operator.yaml#L77

cstor:
  enabled: true

  csiController.driverRegistrar.image.registry: my.private.registry/
  csiController.provisioner.image.registry: my.private.registry/
  csiController.resizer.image.registry: my.private.registry/
  csiController.resizer.image.registry: my.private.registry/
  csiController.snapshotter.image.registry: my.private.registry/
  csiNode.driverRegistrar.image.registry: my.private.registry/
  cspcOperator.cstorPool.image.registry: my.private.registry/
  cspcOperator.cstorPoolExporter.image.registry: my.private.registry/
  cspcOperator.image.registry: my.private.registry/

  imagePullSecrets:
    - name: my-private-registry
