Summary:
The Hermes RuntimeConfig for bridgeless accidentally force-disabled ES6Proxy, resulting in #43523

To fix it, let's remove the incorrect override.

To test using RNTester, add the following change:

   );
   const colorScheme = useColorScheme();
+  new Proxy({}, {});

   const {

     activeModuleTitle,

Before this change, RNTester will get an error at start-up. After, the app loads correctly.
