build(deps): [security] bump ws from 4.1.0 to 6.2.2

[dependabot-preview[bot]]

Bumps ws from 4.1.0 to 6.2.2. This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

ReDoS in Sec-Websocket-Protocol header

Impact

A specially crafted value of the Sec-Websocket-Protocol header can be used to significantly slow down a ws server.

Proof of concept

for (const length of [1000, 2000, 4000, 8000, 16000, 32000]) {
  const value = 'b' + ' '.repeat(length) + 'x';
  const start = process.hrtime.bigint();
value.trim().split(/ *, */);
const end = process.hrtime.bigint();
console.log('length = %d, time = %f ns', length, end - start);
}
