update WebSocket port

[B14ckP4nd4]

based on Binance API Documentation - WebSocket Section the Websocket port for stream prices is "9443" but it's outdated and the current port is 443.
I tested the WebSocket repeatedly and port 9443 didn't work with this package

According to the official Binance Spot WebSocket Streams documentation, both endpoints are valid:

The base endpoint is: wss://stream.binance.com:9443 or wss://stream.binance.com:443.

Source: https://developers.binance.com/docs/binance-spot-api-docs/web-socket-streams

So wss://stream.binance.com:9443 is still documented by Binance, while wss://stream.binance.com:443 can be used as an alternative, especially in environments where port 9443 is blocked.
