fix(kafka): Use wait strategy instead of deprecated wait_for_logs

[Hugo-C]

Related to https://github.com/testcontainers/testcontainers-python/issues/874.

Since those containers first need to be started to know their exposed ports, we cannot use DockerContainer._wait_strategy. We have to keep checking logs manually in their own start methods.

Let me know if there is anything to change.
