⬆️ Bump xterm from 4.3.0 to 4.4.0 in /src

[dependabot-preview]

Bumps xterm from 4.3.0 to 4.4.0.

Release notes

Sourced from xterm's releases.

4.4.0

🚀 Features

• A new addon is available that serializes the buffer as a string, allowing restoring the majority of the state to a new terminal by calling Terminal.write(serializedState). See the xterm-addon-serialize section below for more info.
• A new addon to enable unicode 11 support, which can fix many emoji-width related bugs on modern operating systems. See the xterm-addon-unicode11 section below for more info.
• Support alt-clicking in multi-line prompts in the normal buffer (#2670) via @kumaran-14

📦 API

• Support for some window manipulation/reporting sequences (#2393) via @jerch. These must be enabled explicitly via the new windowOptions option as they have security implications.
• Allow the thickness of the bar cursor to be configured (#2590) via @npezza93

  new Terminal({
    cursorStyle: 'bar',
    cursorBarWidth: 3
  });

• The parser API is now stable (#2689) via @Tyriar
