Fixes #17429

Zulu 21.0.8 appears to have resolved our issues with getting CI green with Java 21. UTs and Quidem Tests now run on 21 latest from zulu.

The verify-java script has been updated to reflect java 11 no longer being supported and java 21 being supported. The java docs have also added 21 in addition to 17 as supported java.

Release Notes

Java 21 is officially supported for Druid runtime.
