fix: correct Linux artifact naming in release notes

- Fix electron-builder Linux package architecture naming differences:
  - AppImage x64: x64 -> x86_64
  - deb x64: x64 -> amd64
  - rpm x64: x64 -> x86_64
  - rpm arm64: arm64 -> aarch64

- Update electron-builder config with separate artifactName for Windows NSIS

- Optimize Windows build config to build x64 and arm64 separately
