Issue Summary

The documentation for Bitbucket Data Center on a Kubernetes cluster shows an incorrect architecture diagram which contradicts Supported Platforms and NFS.md.

Such a diagram can mislead the user about the resulting deployment from HELM charts and cause a significant difference in expenses on the public cloud.
This is reproducible on Data Center: yes.

Steps to Reproduce

Documentation bug

Expected Results

The diagram shows NFS example.

Actual Results

The diagram shows the AWS EFS example.

Workaround

Please don't use the diagram for the expense estimations and build the storage according to NFS example.
