maven: switch to maven.compiler.release

Build with --release instead of -source and -target, to ensure we use the
correct language rules and system classes.  Fixes build warning on
Java > 22:

    Warning:  location of system modules is not set in conjunction with -source 22
      not setting the location of system modules may lead to class files that cannot run on JDK 22
      --release 22 is recommended instead of -source 22 -target 22 because it sets the location of system modules automatically
