Upgrade to JDK 22 javac (build 33).

[lahodaj]

This is a first attempt to upgrade the nb-javac to a new version based on JDK22.

Looks fine. Thanks.

hi @lahodaj. #7019 got merged and CI should be now ready for the NB 22 cycle. Could you make this small additional change which would enable testing on JDK 22? I couldn't do this myself because nb-javac 22 would be required for that - and I think this would fit to this PR.

Adjusted the GH actions, as suggested by @mbien. I'll integrate once the build is green, unless there are objections. Thanks!

awesome! thanks for updating the java version on the hints job, lets hope everything is green on 22-ea.

feel free to merge if everything is ready - master is green again.
