[Resources] `ManagementLockProperties` contains Azure-internal `owner` property

The swagger of `locks`'s `ManagementLockProperties` contains an `owner` property which is only for Azure internal usage according to https://github.com/Azure/azure-cli/issues/22528:

https://github.com/Azure/azure-rest-api-specs/blob/b2de552d860a5cc148c7a0b7a739fd0dacb5b5a4/specification/resources/resource-manager/Microsoft.Authorization/stable/2016-09-01/locks.json#L971-L977

This makes the `owner` property publicly available in

- REST API doc: https://docs.microsoft.com/en-us/rest/api/resources/management-locks/create-or-update-at-resource-group-level#managementlockobject
- ARM template doc: https://docs.microsoft.com/en-us/azure/templates/microsoft.authorization/locks?tabs=json
- Python SDK: https://github.com/Azure/azure-sdk-for-python/blob/830ccf6ab129bdd6b7343cfae39e4e8e4b3bfd4d/sdk/resources/azure-mgmt-resource/azure/mgmt/resource/locks/v2016_09_01/models/_models_py3.py#L68-L69

The swagger should either hide this property or clarifies its internal usage.

Start with specification/resources/resource-manager/Microsoft.Authorization/stable/2016-09-01/locks.json at the ManagementLockProperties definition and inspect the owner property and surrounding swagger metadata. Check how this definition feeds the REST documentation, ARM template documentation, and Python SDK, then confirm whether the owner property should be hidden or explicitly marked for internal use.
