[dependabot]

Bumps ws, engine.io, socket.io-adapter and engine.io-client. These dependencies needed to be updated together.
Updates ws from 8.18.3 to 8.20.1

Release notes

Sourced from ws's releases.

8.20.1

Bug fixes

• Fixed an uninitialized memory disclosure issue in websocket.close() (c0327ec1).

Providing a TypedArray (e.g. Float32Array) as the reason argument for websocket.close(), rather than the supported string or Buffer types, caused uninitialized memory to be disclosed to the remote peer.

import { deepStrictEqual } from 'node:assert';
import { WebSocket, WebSocketServer } from 'ws';
const wss = new WebSocketServer(
{ port: 0, skipUTF8Validation: true },
function () {
const { port } = wss.address();
const ws = new WebSocket(ws://localhost:${port}, {
skipUTF8Validation: true
});
ws.on('close', function (code, reason) {
  deepStrictEqual(reason, Buffer.alloc(80));
});

}
);
wss.on('connection', function (ws) {
ws.close(1000, new Float32Array(20));
});

The issue was privately reported by Nikita Skovoroda.
