Pull request overview

This PR updates the xterm.js dependency set used by VS Code (desktop, remote server, and web) to pick up an upstream fix for the kitty keyboard protocol that regressed key handling (notably Ctrl+C) in the integrated terminal with fish.

Changes:

• Bump @xterm/xterm from 6.1.0-beta.168 → 6.1.0-beta.169 across the repo’s relevant package manifests.
• Bump associated @xterm/addon-* packages to the matching beta.169 set (and @xterm/addon-webgl to 0.20.0-beta.168).
• Update the corresponding package-lock.json files to reflect the new resolved versions, integrity hashes, and peer dependency ranges.
