Windows uninstaller should have option to also remove user data dir and extensions dir

I tried to uninstall / Reinstall Code Insider because of a recurring Error/Crash at "startup/reloaded" (Update / Reboot / proper exit), disabling extensions and remove all custom settings did not fixed it Before re-installing i wanted to be sure i has no crap left that code have hurted Code Insiders .... surprise surprise ....

• VSCode Version: Latest of Code and Code Insider
• OS Version: Windows 10

Steps to Reproduce:

1. Install it
2. Add extensions
3. Change settings
4. Use it
5. Update it
6. Uninstall it
7. Be curious on what's left

On top of that, i uninstalled extensions long time ago and they were still on disk, here is what code-insiders --list-extensions output :
