build(deps): bump socket.io from 2.3.0 to 2.4.1 in /docs

[dependabot]

Bumps socket.io from 2.3.0 to 2.4.1.

Release notes

Sourced from socket.io's releases.

2.4.1

This release reverts the breaking change introduced in 2.4.0 (socketio/socket.io@f78a575).

If you are using Socket.IO v2, you should explicitly allow/disallow cross-origin requests:

• without CORS (server and client are served from the same domain):

io.origins((req, callback) => {
  callback(null, req.headers.origin === undefined); // cross-origin requests will not be allowed
});

• with CORS (server and client are served from distinct domains):

io.origins(["http://localhost:3000"]); // for local development
io.origins(["https://example.com"]);

In any case, please consider upgrading to Socket.IO v3, where this security issue is now fixed (CORS is disabled by default).

Reverts

• fix(security): do not allow all origins by default (a169050)

2.4.0

Related blog post: https://socket.io/blog/socket-io-2-4-0/

Features (from Engine.IO)

• add support for all cookie options (19cc582)
• disable perMessageDeflate by default (5ad2736)

Bug Fixes

• security: do not allow all origins by default (f78a575)
• properly overwrite the query sent in the handshake (d33a619)

⚠️ BREAKING CHANGE ⚠️

Previously, CORS was enabled by default, which meant that a Socket.IO server sent the necessary CORS headers (Access-Control-Allow-xxx) to any domain. This will not be the case anymore, and you now have to explicitly enable it.
