Provide aarch64 binaries

Grain does support m1

When building Grain from source, everything works great on aarch64 Mac computers. We also supply aarch64 Linux docker images: https://github.com/grain-lang/grain/pkgs/container/grain/71393126?tag=main

No CI service provides aarch64 Mac runners and the pkg tool doesn't allow x86 -> aarch64 cross-compiles, so we don't have the ability to build binaries for it.

I'll change your title to "Provide aarch64 binaries" so it is accurately tracking what doesn't currently exist.

Would it be possible to have the Homebrew cask build it from source on ARM instead of defaulting to just downloading the prebuilt x64 binary?

[phated]

@adsouza no, the build tools aren't easily available via brew.

@phated Things have changed and the macos-14, macos-14-xlarge, macos-13-xlarge and macos-latest-xlarge runners are now available for arm64. The first one is available for everyone regardless of any GitHub plan.
