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

[thecmdradama]

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.
