What happened?

When using Java 24, the JNA transitive dependency of the zerodep transport of docker-java produces the following message:

Short of requiring every user of testcontainers-java to add a JVM arg, there is no other option but to switch the docker-java transport to get rid of this warning. Httpclient5 would be a good candidate.

Additional Information

• https://github.com/java-native-access/jna/issues/1665

The issue identifies the Core module but no files or tests. Start by tracing the Core module's docker-java transport dependency and compare the proposed httpclient5 transport; done means Java 24 no longer emits the JNA restricted-access warning while the existing Core behavior remains working.
