Add a build for macos headless server

[huoshenlaile]

Hello developer team.

I’ve been running a Factorio server on macOS (arm64) for quite some time. Apple Silicon processors have much better single-core performance, which actually allows me to run larger maps than on CPUs like the 9950X or 13900K.

However, the current distribution only provides a linux64 headless server. To run the server on macOS, I currently have to manually download the full build, unpack it, adjust paths, and so on each time there is an update.

Would it be possible to provide a macOS headless server build (arm64)? Ideally, it would also be available through a stable download endpoint similar to:
https://factorio.com/get-download/stabl ... ss/linux64
For example:
https://factorio.com/get-download/stabl ... acos-arm64
This would make automated updates and deployment much easier for those running servers on Apple Silicon.
