Incorrect Documentation

Issue

The f flag is missing in the "Example PersistentVolumeClaim" section at https://docs.eidf.ac.uk/services/gpuservice/training/L2_requesting_persistent_volumes/#example-persistentvolumeclaim

You create a persistent volume by passing the yaml file to kubectl like a pod specification yaml kubectl -n <project-namespace> create <PVC specification yaml>

The command should be kubectl -n <project-namespace> create -f <PVC specification yaml>
