Java 22 support and release 1.9.22

[kriegaex]

Java 22 was released yesterday, 2024-03-19. As soon as Eclipse JDT Core has merged the beta 22 branch into its main branch, start merging from there into AspectJ JDT Core, from there into AspectJ and from there into AJDT, which hopefully helps to fix https://github.com/eclipse-aspectj/ajdt/issues/49.
