Now that we have productized Flink 1.19.1, the version Operator 1.10.0 depends on. We can update the sql-runner image to Flink 1.20.
This will require:
- productizing Flink 1.20
- upgrading flink-sql upstream to use flink 1.20 and a 1.20 compatible kafka connector
- productizing a 1.20 flink kafka connector
- updating flink-sql-examples to specify the right flinkVersion
