Add AArch64 macOS build to releases

[golmschenk]

Currently, only the macOS builds only include x86-64 builds. With all new Macs being AArch64, having an AArch64 build would be useful. Hopefully, this would be as simple as adding the following build include to the .github/workflows/release.yml, but I haven't checked this closely.

- build: aarch64-macos
  os: macos-latest
  rust: stable
  target: aarch64-apple-darwin

I agree, this should work. Testing is is always a bit of a pain, but one could do it by forking, activating CI, and then triggering the publish workflow.

Thanks! I wasn't sure if there were additional contributing rules. I did take a quick look at doing this, but it looks like the CI release workflow requires some extra repository configuration (not for this repository, but for the fork repository). When I have some more time, I may take another look, unless someone else gets to it before me.
