Switch to Java 22 + add basic test suite

The tests from Java 21 were copied to 22. Inactive ones were activated
after their features under test were fixed/implemented. Preview ones
were promotes to final ones for unnamed variables and patterns.

TODO: Add tests for new Java 22 features and maybe adjust or
amend existing feature tests, if preview or final characteristics have
changed since Java 21.
