Apple Silicon confirmed working

ARM64 ("Apple Silicon") binaries confirmed to be working on (native) Node.js 15 under macOS Big Sur. Thanks to the excellent GitHub Actions, we could provide native support for this new platform on day 1, without ever needing to buy any Apple hardware. That's a win for the environment, as buying new crap you don't need is a bad habit.
