Every time call Conext.current() will return a different object

Describe the bug

Once we added dependency to this library: io.opentelemetry.instrumentation / opentelemetry-grpc-1.6
It will inject the ContextStorageBridge, with that, it changes the Context.current() behavior, it will return a new Object everytime call the method. That causes various issue such as it breaks the unit test that depends the equality of the Context.

Steps to reproduce

Add dependency to: io.opentelemetry.instrumentation / opentelemetry-grpc-1.6

Run following code:

package org.example;

import io.grpc.Context;
import io.opentelemetry.api.GlobalOpenTelemetry;
import io.opentelemetry.context.Scope;


public class Main {
  public static void main(String[] args) {
    try (Scope scope = GlobalOpenTelemetry.get().getTracer("test").spanBuilder("test").startSpan().makeCurrent()) {
      System.out.println(Context.current().equals(Context.current()));
    }
  }
}

Expected behavior

It prints "false"

Actual behavior

it should print "true"

Javaagent or library instrumentation version

1.64.0

Environment

JDK: Java 17
OS: Mac os

Additional context

No response

The reported entry points are Context.current() and the injected ContextStorageBridge; first run the Java 17 reproduction with opentelemetry-grpc-1.6 and compare repeated current() results. Trace how the bridge supplies the current context, and consider the issue done when repeated calls preserve the expected equality without breaking the instrumentation behavior.
