What happened?

I am upgrading TestContainers from 1.21.3 to 2.0.3 due to the recent changes in the Docker engine that we can no longer (by default) run against latest Docker engine. Most of the issues have been resolved in when running docker localy.

The regression is in the ComposeContainer where the .withLocalCompose(boolean) has been removed in this PR. By doing so it is no longer possible to run docker in docker without having a docker executable in the host docker image.

With the removal of the ComposeContainer.withLocalCompose(boolean) it is no longer possible to influence the localCompose field on the ComposeContainer class which results in that ComposeDelegate.runWithCompose(boolean localCompose, String cmd, Map<String, String> env, List<String> fileCopyInclusions) is always called with localCompose=true. Making it impossible to the ContainerisedDockerCompose strategy

Relevant log output

I have noticed that you can leverage the localCompose boolean by constructing the ComposeContainer with a DockerImageName as a parameter.
