Enhancements to the IACM approval step, specifically to align its functionality with the existing Harness Approval step.

We are requesting for following key features:

Email notifications to User groups: The ability to send email notifications containing details of the IACM plan step to specified user groups.

Restricted Approval based on Executor: Implementation of a mechanism to prevent the user who executed the pipeline from approving the changes implemented by said pipeline.

Dedicated Approval User Group: The ability to define a distinct and authorized user group responsible solely for approving IACM changes.
