Hardcoded path causes notarization to fail on arm64 (and generally different targets)

[nc7s]

Released .app is built for x86_64, electron-builder puts artifacts for it in release/mac. But on arm64 aka M1/2, it's release/mac-arm64. A rather cryptic spawn ditto ENOENT error is thus caused by this line:

breaktimer-app/internals/scripts/Notarize.js

Line 14 in fa042f8

appPath: `release/mac/BreakTimer.app`,

It can of course be fixed with a query into electron-builder, but there's another route: to build a universal binary. This would introduce yet another ~100MiB to the final .app (from Electron Framework), but it's already ~200 anyway. This can be achieved with:

By the way, electron-notarize has changed to @electron/notarize.
