Issue description

The solution's volumesnapshot.yaml creates a snapshot of PVC postgresql-data-clone instead of postgresql-data, thus resulting in a failed grading step.

Steps to reproduce:

Follow the exercise steps, use solution YAML resources instead of editing.

Workaround:

Edit volumesnapshot.yaml manually instead of using the solution.

Expected result:

volumesnapshot.yaml should create a snapshot of postgresql-data volume.
