New helper apps on macOS in Electron v6

• Version: 🤷‍♂

• Target: macOS

This is just a heads up that electron@6 will include two new “Helper.app” applications as a result of a Chromium change and builder needs to be updated to support those two new helpers.

electron-packager commit to handle the new files --> https://github.com/electron/electron-packager/commit/8d407e7b18c9e09f4590667fe28841f0ece974f7

@develar @Evoks I upgraded from Electron5 to 6 (electron-builder to the latest version), when submitted via the Application Loader, it gives these error:
