TxEventQinOracleDB: GraalVM isn't removed in teardown

[andytael]

After running kafka-undeploy there are still docker images left from the HOL:

docker images
REPOSITORY                   TAG                 IMAGE ID            CREATED             SIZE
ghcr.io/graalvm/graalvm-ce   ol8-java11          d063a135bcce        2 months ago        862MB

The following command will remove the images (needs to be added to the kafka-undeploy script:

docker images -a | grep "graalvm-ce" | awk '{print $3}' | xargs docker rmi -f
