Subject: [PATCH] Setup auf KRAFT umgestellt
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

* Der Zookeeper wird dann nicht mehr benötigt.
* Broker-Images auf `bitnami/kafka:3.3.1` umgestellt, da die Confluent-
  Images den KRAFT-Modus noch nicht unterstützen.
* README.sh an die Änderungen angepasst.
