Suppress JVM warnings when running Bazel jars

[LeFrosch]

When running the Starlark REPL it prints the following warnings:

WARNING: A restricted method in java.lang.System has been called
WARNING: java.lang.System::loadLibrary has been called by net.starlark.java.eval.JNI in an unnamed module (file:/home/daniel_brauner/.local/share/JetBrains/CLion2026.2/clwb/bazel/starlark_repl.jar)
WARNING: Use --enable-native-access=ALL-UNNAMED to avoid a warning for callers in this module
WARNING: Restricted methods will be blocked in a future release unless native access is enabled
