At some point during the last 11 months, the bitnami/kafka Docker images began requiring that KAFKA_CFG_NODE_ID be set for KRaft mode. As a result, the Kafka service in .github/workflows/ci.yaml no longer starts, causing the "make test-system ZTEST_TAG=kafka" step to fail by timing out when connecting to Kafka. Fix by setting KAFKA_CFG_NODE_ID.
