We have upgraded our docker-images to use Kafka 3.0.0 from 1.6.x.

The corresponding confluent version that we are using in the docker-images is 6.0.2
(https://github.com/debezium/docker-images/blob/bf144421a20936cb86263c62e71c9b89ec08ef94/connect-base/1.8/Dockerfile#L24)

From the confluent documentation compatibility matrix

https://docs.confluent.io/platform/current/installation/versions-interoperability.html#interoperability-versions
https://docs.confluent.io/platform/current/release-notes/index.html

we need to use confluent version 7.0.x for Kafka 3.0.0
