review test dependency overrides associated with docker-java

[pjfanning]

Unfortunately, docker-java has a lot of outdated dependencies - many with CVEs.

If and when we uptake a new docker-java, we can review if we still need some or all of our sbt dependency overrides associated with docker-java. See https://github.com/apache/pekko/pull/1313 for an example.
