Description

I noticed a PR that failed for Jenkins but not for the GitHub Actions build. 
Tracing it down, it looks like Jenkins was using Scala 2.12 and GitHub actions is using 2.13.

We still should support 2.12, so we should fix the GitHub actions now that Jenkins is removed. Until we fix, folks can merge in code that breaks 2.12 builds.

See Jenkins for failure:https://ci-builds.apache.org/job/Kafka/job/kafka-pr/job/PR-17093/5/cloudbees-pipeline-explorer/?filter=37

see for success in GH Actions: https://github.com/apache/kafka/actions/runs/11039342155/job/30672276597?pr=17093

see raw build for 2.13: https://productionresultssa2.blob.core.windows.net/actions-results/4f08a774-9253-4d15-8617-a627e9961b76/workflow-job-run-716dd2a8-3073-58cf-0d26-4a389b46b592/logs/job/job-logs.txt?rsct=text%2Fplain&se=2024-09-26T01%3A05%3A04Z&sig=klIXSOTwKN9WrBvtdsN6j45DbSqg7ikwow%2FGETJy5pc%3D&ske=2024-09-26T12%3A26%3A46Z&skoid=ca7593d4-ee42-46cd-af88-8b886a2f84eb&sks=b&skt=2024-09-26T00%3A26%3A46Z&sktid=398a6654-997b-47e9-b12b-9515b896b4de&skv=2024-05-04&sp=r&spr=https&sr=b&st=2024-09-26T00%3A54%3A59Z&sv=2024-05-04
