ZeebeVolumes are not cleaned up by Ryuk

[lenaschoenburg]

While debugging some disk usage issues in camunda/camunda#16619, I've noticed thousands of leaked volumes that did not get cleaned up by Ryuk.

The ZeebeVolume does apply some labels that are supposed to mark it for Ryuk:

zeebe-test-container/core/src/main/java/io/zeebe/containers/ZeebeVolume.java

Lines 164 to 165 in f108854

	final CreateVolumeResponse response =
	configurator.apply(command.withLabels(DockerClientFactory.DEFAULT_LABELS)).exec();

These default labels look like this:

However, testcontainers-java sends Ryuk the following labels:
https://github.com/testcontainers/testcontainers-java/blob/33c904ed9c23088d725dd0b5f017cdab2384edae/core/src/main/java/org/testcontainers/utility/ResourceReaper.java#L44-L56

As you can see, the TESTCONTAINERS_SESSION_ID_LABEL is missing from the ZeebeVolume labels.
And indeed, if I modify the volume with, they get cleaned up by Ryuk as expected.

ZeebeVolume.newVolume(
    cfg -> {
      final var labels = new HashMap<>(cfg.getLabels());
      labels.put(
          DockerClientFactory.TESTCONTAINERS_SESSION_ID_LABEL,
          DockerClientFactory.SESSION_ID);
      return cfg.withLabels(labels);
    });
