Merge pull request 'Add macOS target and platform-qualified artifact names' (#2) from release/v1.0.0 into main

Adds a mac zip target (x64 + arm64) so releases cover all three
platforms. Builds unsigned: electron-builder skips code signing when not
running on macOS, so these need the quarantine attribute cleared.

Also puts ${os} in artifactName. Without it the Windows and macOS zips
were both WhatsThatMusic-1.0.0-x64.zip, which collide as release assets
and give no clue which platform they are.
