Update to the latest Garbage collector that is now supported in Java 21.

Test if there are issues when applied that show in the logs on Docker Startup. Can review all Java Paramters that are reported when a postman job is startup up to ensure these are being picked up.

Cloud engineering will need to assess any positive impact of these settings on memory utilisation and performance over time.
