build(electron): add nsis script for windows installer (#6674)

This pr only includes how to bundle the app into an installer after package step.

todo (not in this pr)
- [ ] make sure updater can work for both nsis & squirrel
- [ ] integrate nsis build into github action workflow

Advantage over Squirrel:
- allowing user to specify the installation location
- better uninstaller
