Use maintained Kafka client in KafkaContainer tests

[joebowbeer]

The KafkaContainer currently has a dev dependency on kafkajs, which is no longer maintained

tulios/kafkajs#1753

I suggest migrating the tests to a supported SDK such as Confluent's or Platformatic's

• https://github.com/confluentinc/confluent-kafka-javascript
• https://github.com/platformatic/kafka

I volunteer to do this.
