fix: add --add-opens java.io and --enable-native-access JVM flags

[romanisb]

Follow-up on the Java 21 migration.

The two new flags added everywhere:

--add-opens=java.base/java.io=ALL-UNNAMED; fixes IOException.serialVersionUID XStream reflection
--enable-native-access=ALL-UNNAMED; suppresses JNA System::load warning log entries

Testing done

• Ensure you have provided tests that demonstrate the feature works or the issue is fixed

@oleg-nenashev should be the last missing configuration. Let me know if there is something else I could test.

And as already mentioned in another PR. A new release would be much appreciated.
