fix(app-builder-lib): bump @electron/universal to 1.2.1

[bradrees]

Currently it cannot build an Electron 18 Universal (Mac) app:

Expected all non-binary files to have identical SHAs when creating a universal build but "Contents/Frameworks/Electron Framework.framework/Versions/A/Resources/MainMenu.nib/keyedobjects-101300.nib"

Universal 1.2.1 has a fix for this, so bumping the version here too.
