Enable string de-duplication JVM option per default

Description

String de-duplication was originally only supported with G1GC, but was ported to ParallelGC in Java 18: https://tschatzl.github.io/2022/03/14/jdk18-g1-parallel-gc-changes.html

Running DT with -Xlog:stringdedup*=debug (originally -XX:+PrintStringDeduplicationStatistics) tells me that the JVM is able to de-dupe >60% of strings on average.
