Jira issue: CRDB-68397

Start with the roachtest artifacts and logs linked in the report, then inspect pkg/cmd/roachtest/README.md and the reported locations cluster.go:4230 and pebble/version_set.go:456. Determine why the basalt storage test encounters an unsupported protocol version and verify that the kv0 configuration completes without fatal log entries.
