[GONRG-9896] Limit helm release cleanup to partition

devops/gc/tests/clean_up/clean_up.sh

 #!/usr/bin/env bash
+# # This script performs cleanup operations for Kubernetes and Datastore test environments.

+# clean up Datastore entries, or both. The Helm releases to be deleted are filtered
+# based on a configurable variable GC_TEST_HELM_NAME, which defaults to "partition".
