Problem description :

Update an existing endpoint rule is not supported for Azure.
When trying to update the domain list of the rule, it throws an error :

Error: cannot update mws ncc private endpoint rule: Updating fields enabled for Azure private endpoint rule 4e569a53-xxx-xxx-xxxx-39907e327bf2 is not supported. No updates were attempted.

According the to code mws/resource_mws_ncc_private_endpoint_rule.go
it seems that update is only supported on AWS. Currently on Azure, databricks starts to support App Gateway as target, the provider should allow update on the endpoint rules on Azure

Steps to Reproduce

1. changing the domain list in the databricks_mws_ncc_private_endpoint_rule resource
2. run terraform apply

Terraform and provider versions

1.100.0
