Isai 9640ecb3fe [Rule Tuning] AWS RDS Instance/Cluster Deletion (#1916)
* add RDS instance deletion to aws rule

I've added to this rule to improve coverage. Currently we detect creation and stopping of RDS clusters and instances. But, we only detect for the deletion of clusters, not instances. This adds the deletion of RDS instances to the detection.

* Update rules/integrations/aws/impact_rds_instance_cluster_deletion.toml
