kafka: ERROR Unable to resolve address: host.docker.internal

[Vinicius Antonio do Nascimento]

I'm following exactly the way it is described in the README https://hub.docker.com/r/ubuntu/kafka and can't get the ubuntu kafka container up.

ps.: i also tried changing the env var ZOOKEEPER_HOST to localhost or 0.0.0.0.

Please close this issue.

Although the README says to run like this:

```
docker run -d --name kafka-container -e TZ=UTC -p 9092:9092 -e ZOOKEEPER_HOST=host.docker.internal ubuntu/kafka:3.1-22.04_beta
```

it was only possible to run on ubuntu 20.04 like this:

```
docker run -d --name kafka -e TZ=UTC -e -p 9092:9092 -e ZOOKEEPER_HOST=172.17.0.1 -e ZOOKEEPER_PORT=2181 ubuntu/kafka:3.1-22.04_beta
```

This seems to be related with the system's Docker networking configurations. "host.docker.internal" is a typical DNS for those using Docker Desktop, for example.

I'll assign Paulo to this ticket anyway (but I think it can be closed)
