Desktop: build universal app for macOS X

[runchard]

This PR will make the Joplin desktop app running in both intel and M1 chip both natively.

This is an electron feature support from version 11.0.0.

How do I test it?

Currently, Apple Silicon applications only run on Apple Silicon hardware, which isn't commercially available at the time.

PS: I've use it in my silicon version Macbook pro for several days.

The linked article says we'd need to ship two versions of the app, but your change seems to mean you remove the dmg and replaced by something else.

I do not want a universal binary on macOS. This BS was finally over and now they started again with this crap.

I rather have 2 dmg for the respective architectures.

[laurent22]

Yes, perhaps two versions would be fine, but even that I'm not sure. We don't quite have the resources to deal with all the rubbish coming from Apple, from the insane iOS release process, to the idiotic notarisation. That would be adding yet one more way things can fail, so that's why I'm not so keen on it, unless it becomes really necessary.

[tessus]

Yes, the Apple release pipeline is a joke. Not to mention the deprecation of APIs without proper replacements, the lack of proper runtime/compile messages, .... Apple took the fun out of developing for Apple. That's why I'm no longer writing code for macOS.

[runchard]

Make sense, separate bundle can make dmg smaller and less prone to complex errors.

Ok thanks for looking into it but at that point we probably won't add this. It probably requires more testing on CI and we don't really have the resources for it.
