[PM-9207] Fix desktop builds by installing Python setuptools

🎟️ Tracking

The updates to the argon2 package seem to have broken the MacOS desktop builds, as they are missing the Python package setuptools.

To fix the builds, I've added the package to build-desktop.yml, just like it already is in release-desktop-beta.yml
