fix(engine.io-client): correctly consume the ws package (#5220)

This should fix the following issue:

```
SyntaxError: Named export 'WebSocket' not found. The requested module 'ws' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'ws';
const { WebSocket } = pkg;
```
