Since #48, the Java JVM config was shared by all three variants, with generated heap size values.

On some machines (e.g. GHA Runners) these values were incompatible with the other generated memory configs, and the Coordinator container would often fail on startup, thus causing CI runs to fail because they couldn't run the Integrity Tests.

This PR splits the JVM config again so that the original 24GB values can always be used in Java Worker mode.

This in conjunction with #108 will fix the Presto Nightly CI.
