Azure CLI version 2.57 az backup create failure

### Describe the bug

I tried using the cli create a backup policy for my Azure File Share, and no matter how the command was issued. Here are the commands I tried after creating my storage account and vault:
azureuser:~$ az backup policy create --backup-management-type AzureStorage --name DailyPolicy --policy "{ \"type\": \"AzureFileShare \", \"schedulePolicy\": { \"scheduleRunDays\": [\"Sun\", \"Mon\", \"Tue\", \"Wed\", \"Thu\", \"Fri\", \"Sat\"], \"scheduleRunFrequency\": \"Daily\", \"scheduleRunTimes\": [\"19:30\"] }, \"retentionPolicy\": { \"dailySchedule\": [ { \"retentionDurationCount\": 30, \"retentionDuration\": \"Days\", \"dailyRetentionFormat\": \"at7:30PM\" } ] }}" --resource-group my-resource-group --vault-name myRecoveryServicesVault --workload-type AzureFileShare

### Related command

az backup policy create \
--backup-management-type AzureStorage \
--name DailyPolicy \
--policy "/c/temp2/DailyPolicy.json" \
--resource-group my-resource-group \
--subscription 9f21ef71-545e-49b9-90ae-b90019419808 \
--vault-name myRecoveryServicesVault

##### I even made the json file simpler like this

azureuser:~$ cat /c/temp2/DailyPolicy.json
{
"type": "AzureFileShare",
"backupManagementType": "AzureStorage",
"schedulePolicy": {
"scheduleRunDays": ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"],
"scheduleRunFrequency": "Daily",
"scheduleRunTimes": ["19:30"]
},
"retentionPolicy": {
"dailySchedule": [
{
"retentionDurationCount": 30,
"retentionDuration": "Days"
}
]
}
}

### Errors

The command failed with an unexpected error. Here is the traceback:
'NoneType' object has no attribute 'backup_management_type'

### Expected behavior

I was hoping I could have my policy created with CLI so I could complete my project.

### Environment Summary

azureuser:~$ az --version
azure-cli 2.57.0

core 2.57.0
telemetry 1.1.0

Extensions:
dataprotection 0.11.2

Dependencies:
msal 1.26.0
azure-mgmt-resource 23.1.0b2

Python location 'C:\Program Files\Microsoft SDKs\Azure\CLI2\python.exe'
Extensions directory 'C:\Users\franc\.azure\cliextensions'

Python (Windows) 3.11.7 (tags/v3.11.7:fa7a6f2, Dec 4 2023, 19:24:49) [MSC v.1937 64 bit (AMD64)]

Legal docs and information: aka.ms/AzureCliLegal

Your CLI is up-to-date.

### Additional context

I added the az dataprotection for an alternative but it is only a work around that I have not had the chance to play with it since it is still in the experimental stage.
