fix(java): remove conflicting reflection configuration to address UnsupportedFeatureException with GraalVM 22.1.0

[mpeddada1]

Reproducer of issue: suztomo/pubsub-sample-graal22.1-failure#1.

The registration of java.lang.management.ManagementFactory was the root cause of the following problem in Pub/Sub and other libraries:

Fatal error: org.graalvm.compiler.debug.GraalError: com.oracle.graal.pointsto.constraints.UnsupportedFeatureException: Detected a PlatformManagedObject (a MXBean defined by the virtual machine) in the image heap. This bean is introspecting the VM that runs the image builder, i.e., a VM instance that is no longer available at image runtime. Class of disallowed object: com.sun.management.internal.HotSpotDiagnostic  To see how this object got instantiated use --trace-object-instantiation=com.sun.management.internal.HotSpotDiagnostic. The object was probably created by a class initializer and is reachable from a static field. You can request class initialization at image runtime by using the option --initialize-at-run-time=<class-name>. Or you can write your own initialization methods and call them explicitly from your main entry point.

The configuration appears to have been added in an initial commit to support grpc-netty-shaded but no longer seems necessary. The fix has been verified locally with the Pub/Sub (which depends on grpc-netty) integration tests and sample.

Nice detective work!
Is RuntimeMXBean still needed?
