Use name placeholder instead of an arbitrary value for storage name

This version is less likely to confuse the users and is more consistent with the rest of the doc.

I think when the documentation was written the included storage account name should have been replaced with the <STORAGE_NAME> placeholder. I presume it was simply forgotten or is an artifact of an old version of the documentation
