Change Details

After upgrading jobs to flink 1.20 (T376812) we should consider also upgrading the jobs to support java 17. Java 17 is marked as experimental with flink 1.20 but fully supported in flink 2. To ease operations of the flink image where we'd like to no longer support java11 we might try to test and see if java17 is working for our jobs running flink 1.20 Actual work will need to happen in separate subtasks: * [x] T400600: flink 1.20 base image with java 17: docker-registry.wikimedia.org/flink:1.20.2-wmf1-20250912 * [][TODO] test build eventutilities with java 17 * [] T404417 upgrade SUP to java 17 * [] [TODO] upgrade rdf-streaming-updater to java 17 * [] [TODO] upgrade dse enrichment jobs to java 17 AC: * all flink deployments run on java 17
