Fixed code and reason arguments ignored when closing a WebSocket on iOS (#24950)

Summary:
While working on #24893 I noticed the `WebSocket` module implementation on iOS was ignoring the code and reason arguments for the `close` method.
The Android implementation already handled those arguments properly.
So this PR brings iOS implementation on par with Android for the `WebSocket` module.

## Changelog

[iOS] [Fixed] - Fixed `code` and `reason` arguments ignored on iOS when calling `WebSocket.close`
