…acebook#56801) Summary: In preparation for enabling `enableSyncVoidMethods` (D104331837), which makes TurboModule void methods execute synchronously on the JS thread instead of being dispatched asynchronously. Currently, this module overrides `methodQueue` to return `dispatch_get_main_queue()` so its void methods execute on the main thread. When `enableSyncVoidMethods` is enabled, the `methodQueue` override is ignored for void methods — they execute directly on the JS thread. This causes crashes for any UI operations that must run on the main thread. **Fix:** Remove the `methodQueue` override. The `alertWithArgs` method already dispatches UI work onto the main thread via `RCTExecuteOnMainQueue`, so it is already safe.
