Parsing Java internal version of Zulu JVM breaks FlightRecordingSupportRule

The FlightRecordingSupportRule does not work with JFR files from Zulu JVM. The regex parsing the Java internal version (RulesToolkit.getJavaVersion()) can't parse the one from Zulu JVM.

NB: the Java internal version can be obtain with java -Xinternalversion.

Here are a list of some Java internal version each major version of Java for the Zulu JVM:
