[ISSUE] Experimental exporter generates permissions for /shared in the workspace

[rohitnijhawan]

The Experimental exporter generates permissions for the /shared directory in the databricks workspace.

As a result, the terraform apply operation tries to apply permissions - such an operation is not supported.

The following resource definition

resource "databricks_permissions" "directory_shared_430507847510155" {
  directory_id = data.databricks_directory.shared_430507847510155.object_id
  access_control {
    permission_level = "CAN_MANAGE"
    group_name       = data.databricks_group.users_54623195191167.display_name
  }
}

leads to this error

Error: cannot create permissions: Cannot modify permissions of directory 357400256613881
