Enable Kafka test container logging temporarily for build monitoring

I have temporarily enabled STRIMZI_TEST_CONTAINER_LOGGING_ENABLED=true in the test configuration to capture Kafka broker logs. The goal is to monitor the state of the build and have access to detailed Kafka logs in case any errors occur.

This change is intended to stay for about two weeks.
If no related issues appear during that period, the logging will be disabled again (false) to reduce noise.
