fix(ci): regenerate lockfile for cross-platform optional deps

npm/cli#4828 caused package-lock.json to prune platform variants
not matching the local OS. Regenerated from scratch so Windows CI
gets @tauri-apps/cli-win32-x64-msvc and lightningcss-win32-x64-msvc.

Removed the lightningcss Windows install workaround from desktop
workflow. Removed deprecated asyncRequireModulePath from metro config.
