Microsoft.Automation/automationAccounts/variables@2023-11-01- does not show VALUES when isEncrypted = True

**Bicep version**

**Describe the bug**
This API call is performed from Azure Automation Account sandbox.

When trying to use the following API to fecth variables it is only reporting values when variables are not encrypted:

"GET /subscripitons/XXXXXXXXX-xxxx-XXXX-xxx-xxxxxxxxxx/resourceGroups/rg-automation/providers/Microsoft.Automation/automationAccounts/XXXXXXX/variables?api-version=2023-11-01 HTTP/11" 200 1710

{
'value': [
{
'id': '/subscripitons/XXXXXXXXX-xxxx-XXXX-xxx-xxxxxxxxxx/resourceGroups/rg-automation/providers/Microsoft.Automation/automationAccounts/XXXXXXX/variables/mailfrom',
'name': 'mailfrom',
'type': 'Microsoft.Automation/AutomationAccounts/Variables',
'properties': {

'isEncrypted': False,
'value': '"mbox@box.com"',
'description': ''
}
},
{
'id': '/subscripitons/XXXXXXXXX-xxxx-XXXX-xxx-xxxxxxxxxx/resourceGroups/rg-automation/providers/Microsoft.Automation/automationAccounts/XXXXXXX/variables/testvar',
'name': 'testvar',
'type': 'Microsoft.Automation/AutomationAccounts/Variables',

'lastModifiedTime': '2024-11-07T20:22:32.553+00:00',
'isEncrypted': True,
'description': ''
}
}
]
}

**To Reproduce**
curl to:
$ curl https://management.azure.com/subscripitons/XXXXXXXXX-xxxx-XXXX-xxx-xxxxxxxxxx/resourceGroups/rg-automation/providers/Microsoft.Automation/automationAccounts/XXXXXXX/variables?api-version=2023-11-01

**Additional context**
This is a bug in the https://management.azure.com API for Microsoft.Automation/automationAccounts than in the bicep software.

No repository file or test is identified in the issue. Start by reproducing the Microsoft.Automation variables request with the supplied curl pattern and verify whether encrypted values are intentionally omitted; done means establishing whether a change belongs in this repository or in the Azure API.
