Create universal mac app

refs #255

I'm not 100% sure if this is how this is supposed to be implemented as the docs are a bit vague. I was hoping we could try it between your and my computer.

your app should work flawlessly once you update the target architecture to arm64.

I'm not sure if we need to specifically build two apps and call merge somehow or if forge will do it just because? It's all a little unclear based on the docs and I can't find any examples.

You will need to ship two versions of your app: one for x64 (Intel Mac) and one for arm64 (Apple Silicon). The good news is that electron-packager, electron-rebuild and electron-forge already support targeting the arm64 architecture. As long as you're running the latest versions of those packages, your app should work flawlessly once you update the target architecture to arm64.

Update: This package is now available at @electron/universal. You can use it to merge two packaged x64 and arm64 apps into a single binary.

Ya, I'm not sure how installing @electron/universal will somehow let forge know that we want to us it. How do you want me to test this out? It runs in development locally without any issues, but so did the last version. Running npm run make fails with a code signing error.

The docs make it sound magical but you're right, it probably needs some configuration or post processing?

We might need to make the code signing work locally with the certs etc or create a test app and borrow our CI pipeline to not disrupt current production?
