Announcing tfrun import for Sentinel in Terraform Enterprise and Cloud

The `tfrun` import in HashiCorp Sentinel allows policy authors to access context data from the run itself, enabling more flexible and fine-grained enforcement of policies. This includes features such as tag enforcement, where workspace details can be enforced upon resources, fine-grained exceptions that allow for skipping or applying partial policies based on workspace, and enforcing cost controls by limiting budget increases. These new capabilities are now available to all Terraform Cloud and Enterprise customers, expanding the scope of what is possible with Sentinel policies.
