Remove -Djava.security.manager=allow from the products

- Define an unconfigure touchpoint to remove
-Djava.security.manager=allow from the eclipse.ini which is done to
ensure that updates will leave installations in a state that can run
with Java 24.
- Do the above for both products and ensure that both products specify
-Dosgi.requiredJavaVersion=21
