Feature Request: Add `datadog_cloud_workload_security_agent_default_rule` resource

[mrtc0]

We want to manage changes to the `enabled field of the default rules in CWS Agent Configuration.

Currently, the expression field is a required field in the datadog_cloud_workload_security_agent_rule resource.
As a result, attempting to modify the default rules results in a 400 error in the Datadog API, preventing the management of default rules with Terraform.

Are there any plans to support resources like datadog_cloud_workload_security_agent_default_rule similar to datadog_security_monitoring_default_rule ?
