build: replace MakerSquirrel with MakerZIP for Windows

- Remove @electron-forge/maker-squirrel dependency
- Squirrel.Windows fails on modern Windows GitHub Actions runners with Win32Exception during zip creation
- We already use MakerWix which produces a much better .msi installer for Windows users
- Add MakerZIP support for win32 to provide a portable alternative alongside the MSI
