Feature: Upgrade Electron to >= v11 for Apple Silicon (M1) support

[tkain]

The Electron builds for Apple M1 support are only available since 11.0.0 (as described here: https://www.electronjs.org/blog/electron-11-0), and would otherwise get error when installing:

GotError [HTTPError]: Response code 404 (Not Found) for
https://github.com/electron/electron/releases/download/v8.5.5/electron-v8.5.5-darwin-arm64.zip

It'd be great if you can upgrade to Electron v11 (or even latest) and start supporting Apple Silicon natively.

Thanks!
