Kubeflow Filestore documentation is out dated

[SinaChavoshi]

Documentation instructions refer to using KS.. this can be simply done with Kubectl and directly deploying yamls for pv / and pvc.

Documentation link: https://www.kubeflow.org/docs/gke/cloud-filestore/

Example for out dated documentation :
cd //${KFAPP}/ks_app
ks generate google-cloud-filestore-pv google-cloud-filestore-pv --name="kubeflow-gcfs"
--storageCapacity="${GCFS_STORAGE}"
--serverIP="${GCFS_INSTANCE_IP_ADDRESS}"
