Update Build SWT Natives launch to Java 21

[jonahgraham]

Eclipse SWT now uses Tycho 5.x which means we need to run Maven with Java 21

The change to Tycho 5 was a couple of months ago, but I didn't have Java 17 in my Installed JREs so Eclipse was automatically using Java21. Now with a Java17 JRE available I get the below error when launching Build-SWT-native-binaries-for-running-platform

error
