[dependabot-preview]

Bumps xterm from 3.14.5 to 4.12.0.

Release notes

Sourced from xterm's releases.

4.12.0

🚀 Features

• Double click to select a word will now use link providers registered via the API (#3230) via @​marvinthepa
• Support the ligatures addon with the DOM renderer (#3285) and WebGL renderer (#3286) via @​Tyriar

📦 API

• Support async parser handlers (#3222, #3256, #3257, #3267) via @​jerch. This enables for example custom parser handlers to defer heavy work to a worker thread. Note that this will block the terminal and you should generally stay away from this API unless it's a lot of work that would block the UI thread.

  // Handle \x1b[<params>+Z using an asynchronous handler
  terminal.parser.registerCsiHandler({intermediates:'+', final: 'Z'}, async params => {
    await new Promise(res => setTimeout(res, 50));
    return false;
  });

• Add onBell event API so embedders can handle the bell however they want (#3290, #3295) via @​bmf-ribeiro

  terminal.onBell(() => customBellImpl());
