Include docker-java-api in BOM

docker-java-api is part of the (advanced) public API of Testcontainers and thus it seems appropriate and helpful to have it be part of the BOM.

In my use case, I wanted to override GenericContainer.containerIsStarted(), which means I have a compile time dependency on InspectContainerResponse(as it is a parameter) and thus must declare a dependency on docker-java-api.

The problem is that I need to supply a version for the dependency, but what version do I use use? The answer is that it must be the same version as used by Testcontainers, but there's no way to do it automatically, so I have to manually copy/paste the version and keep it updated whenever I update Testcontainers. If it was in the BOM, I could simply add the dependency without a version and it would always be correct.

Das Issue nennt keine Dateien oder Tests. Beginne damit, die BOM-Definition und die vorhandene docker-java-api-Abhängigkeit/-Version zu finden; füge das Artefakt zu den verwalteten Abhängigkeiten hinzu, damit Verbraucher seine Version weglassen können, und überprüfe anschließend, dass die BOM dieselbe Version auflöst, die von Testcontainers verwendet wird.
