chore(deps): bump ws from 7.4.4 to 8.1.0

[dependabot]

Bumps ws from 7.4.4 to 8.1.0.

Release notes

Sourced from [ws's releases](https://github.com/websockets/ws/releases).

8.1.0

Features

• Added ability to skip UTF-8 validation ([#1928](https://github-redirect.dependabot.com/Add ability to skip UTF-8 validation websockets/ws#1928)).

Bug fixes

• Fixed an issue with a breaking change in Node.js master (6a72da3e).
• Fixed a misleading error message (c95e695d).

8.0.0

Breaking changes

• The WebSocket constructor now throws a SyntaxError if any of the subprotocol names are invalid or duplicated (0aecf0c9).

• The server now aborts the opening handshake if an invalid Sec-WebSocket-Protocol header field value is received (1877ddeb).

• The protocols argument of handleProtocols hook is no longer an Array but a Set (1877ddeb).

• The opening handshake is now aborted if the Sec-WebSocket-Extensions header field value is empty or it begins or ends with a white space (e814110e).

• Dropped support for Node.js < 10.0.0 (552b5067).

• The WebSocket constructor now throws a SyntaxError if the connection URL contains a fragment identifier or if the URL's protocol is not one of 'ws:', 'wss:', or 'ws+unix:' (ebea038f).

• Text messages and close reasons are no longer decoded to strings. They are passed as Buffers to the listeners of their respective events. The listeners of the 'message' event now take a boolean argument specifying whether or not the message is binary (e173423c).

  Existing code can be migrated by decoding the buffer explicitly.

  websocket.on('message', function message(data, isBinary) {
    const message = isBinary ? data : data.toString();
    // Continue as before.
  });
  websocket.on('close', function close(code, data) {
  const reason = data.toString();
  // Continue as before.
  });

• The package now uses an ES module wrapper (78adf5f7).

• WebSocketServer.prototype.close() no longer closes existing connections (df7de574).

  Existing code can be migrated by closing the connections manually.
