Keyboard.addListener ignores its context argument

Description

The public Keyboard.addListener(eventType, listener, context?) signature accepts a listener context, but the implementation forwards only the event type and callback to NativeEventEmitter. The supplied context is therefore silently discarded.

Expected behavior

When a context is supplied, keyboard event callbacks should run with that object as this, matching the underlying NativeEventEmitter contract.

React Native Version

0.87.1 and current main

Affected Platforms

JavaScript runtime - All

从公开的 Keyboard.addListener(eventType, listener, context?) 入口点开始，跟踪它如何将参数转发给 NativeEventEmitter。验证提供了 context 的回调是否会以该对象作为 this 执行，同时在未提供 context 时保持现有行为不变。
