Short description of the issue/suggestion:
MacOS SCRIPT and UNIVERSAL stubs both run as x64 (Intel as indicated in Activity Monitor) on an ARM64 machine. Explicitly setting macStartup = "ARM64" produces a .app that runs as Apple

Steps to reproduce the issue/enhancement:

1. On an Apple Silicon mac, package application into .app using the default macStartup of SCRIPT or explicitly set to UNIVERSAL
2. Run produced .app

What is the expected behavior?
Activity monitor shows application is running as Apple

What is the current behavior?
Activity monitor shows application is running as Intel

Hi @idontusenumbers!
It seems that Mac OS 15+ has broken JP, since there are a lot of similar issues related to this one😢
@maths22 has contributed to JP with a nativeJavaApplicationStub. Please, read this comment in issue #448 and test it if possible.
Thanks!!

P.S.: I don't have a Mac anymore, so is very difficult for me to test it by myself.
