az policy remediation create, breaking change in 2.45.0?

**Related command**
az policy remediation create

**Describe the bug**
We get an InvalidRequestContent error after the windows agent picked up the latest version of the Azure CLI.

ERROR: (InvalidRequestContent) The request content was invalid and could not be deserialized: 'Required property 'properties' not found in JSON. Path '', line 1, position 2.'.
Code: InvalidRequestContent
Message: The request content was invalid and could not be deserialized: 'Required property 'properties' not found in JSON. Path '', line 1, position 2.'.

We run the command `az policy remediation create --name -n --policy-assignment -a` in an AzureCLI@2 task with a powershell inlinescript.

**To Reproduce**
I get the same error when running this locally or trough the pipeline:
`az policy remediation create --name -n --policy-assignment -a`

**Expected behavior**
A remediation task should be created with no error.

**Environment summary**
Microsoft-hosted agents, CLI version latest (2.45.0) AzureCLI@2
