Create an universal arch macos build

[Thykof]

Context
Describe / explain why we should do this: motivations, context or other info. Keep it brief and simple - PM

Currently, we built the application for macos arm and amd architectures. We end up with 2 release assets for Mac users: on the landing page, the user has the chose between Macos amd and apple M1/M2 chip (arm).

The goal is to simplify that by proposing a single file. That will allow us to use the feature of detecting the OS of the system and showing to the user a single direct download button.

User flow
Describe the user flow using user stories so the end result is super clear - PM

In the CI, build the application for arm and amd as we do right now and add a step to create a universal built using https://ss64.com/osx/lipo.html

The end user will download the installer that will work for both arm and amd CPU architectures.
