Update github release runner to include macos arm64

Previously, the github `macos-latest` runner was still an amd64/x86_64
architecture. As such we were not able to have a purely Apple Silicon
build through the github release workflow. However, the `macos-latest`
runner is now supported by Apple Silicon[1][2]. As such we need to
create a specific build target for it in `.github/workflows/release.yml`
as well as update the `build_macos_amd64` target to use the `macos-13`
runner such that that architecture is still being built.

This will add an extra artifact to the releases which should allow for
an easier and perhaps more seamless homebrew release process.
