fix: Update avm/res/net-app/net-app-account - fix optional zone for volumes and specify protocolTypes options (#4469)

## Description
This PR resolves the following issues in the
`avm/res/net-app/net-app-account` module
* On the NetApp Volume submodule, `zone` has been renamed to
`availabilityZone`.
* The type for `availabilityZone` has been changed to `string` from
`int[]` and is now optional with null as the default. Previously the
module would try and deploy a volume into all three zones if no value is
defined.
* Changed: `protocolTypes` is now an optional array of strings with
three possible options `'NFSv3', 'NFSv4.1', and 'CIFS'`. If no value is
provided, the default value of `['NFSv3']` is used.
* Added to the description for `protocolTypes` indicating that the user
will need to specify `['NFSv3','CIFS']` or `['NFSv4.1','CIFS']` if
creating dual-stack volumes.
* Added in additional submodule README.md and main.json files generated
by Set-AVMModule.
