Do we need to add any tests that ensure this behavior for any of the metrics present in that PrometheusRule resource in the e2e suite to ensure we don't regress?

It wouldn't hurt to have a test case that checks that those alerts fire when we expect and adhere to the standards linked above (with the summary and description being present). That would also make sure, like you said, that we don't remove this in the future.
