roachtest: multi-region/super-region-failover failed

**Note:** This build has runtime assertions enabled. If the same failure was hit in a run without assertions enabled, there should be a similar failure without this message. If there isn't one, then this failure is likely due to an assertion violation or (assertion) timeout.

Jira issue: CRDB-67962

Start with pkg/cmd/roachtest and the failure at super_region_failover.go:526, then inspect the run_1 artifacts and logs linked in the issue. Compare the lease-verification timeout with the Grafana and Datadog data for this GCE run. Done means determining the failure cause and resolving it so multi-region/super-region-failover completes successfully.
