[Bug] Xmx not passed to script JVM

[skirge]

Describe the bug

-J-Xmx flag is not passed to JVM which is running script

To Reproduce
Steps to reproduce the behavior:

1. invoke joern with -J-Xmx24G --script somescript.sc
2. run ps and notice that java process running replpp.scripting.NonForkingScriptRunner is missing -Xmx flag provided on command line

I think that ScriptRunning.exec is not passing additional JVM command line arguments to created java process.
As a result analysis crashes with OutOfMemory error despite providing flag on command line to increase heap to maximum.

Expected behavior
Xmx flag should be passed to jvm running the script
