Incompatible JVM versions in the jenkins log

[sxa]

While some of the machines, such as Solaris10, cannot have a later JVM installed, there are a number of agent systems in our jenkins which are still running pre-17 JREs for the jenkins agent. During the most recent jenkins upgrade the Versions Node Plugin took them all offline. While we have now changed the configuration so that it won't do this (Set Don't mark agents temporarily offline in the configuration) we should use this opportunity to look at updating the versions for anything not on 17 which can be updated.

Found during the latest jenkins update

[sxa]

With the merging of #3073 we should be able to get these all (other than Solaris) updated to the latest LTS (JDK21)

[steelhead31]

The installer gradles may also need attention if the default JDKs move up to JDK21. Currently they run with JDK17
