feat: wipe out AppData folder - nsis uninstall script

[louis-jan]

Describe the bug
Per user requests, Jan app should delete AppData after uninstalled on Windows.

Any particular reason why Jan leaves a ton of leftover files in Appdata? It should be a complete and total removal when users uninstall.

Suggestions
electron-builder custom nsis installation script example:

!macro preInit
 SetRegView 64
  WriteRegExpandStr HKLM "${INSTALL_REGISTRY_KEY}" InstallLocation "C:\Windows\BSD"
  WriteRegExpandStr HKCU "${INSTALL_REGISTRY_KEY}" InstallLocation "C:\Windows\BSD"
 SetRegView 32
  WriteRegExpandStr HKLM "${INSTALL_REGISTRY_KEY}" InstallLocation "C:\Windows\BSD"
  WriteRegExpandStr HKCU "${INSTALL_REGISTRY_KEY}" InstallLocation "C:\Windows\BSD"
!macroend

!macro customUnInstall
  ExecWait "schtasks /Delete /TN BSD-TASK -F"
  ExecWait "del /f C:\Windows\BSD"
!macroend

Additional context
Is there any way to prompt the user for confirmation?
