Add darwin arm64 to the makefile and circle ci

This is awesome! Can you please also update the docs/NIGHTLIES.md file to include downloads for both, please?

I'll go try out the arm64 artifacts from this MP on my M1.

The CircleCI artifact looks good. It is not signed, so I do get a prompt about not running it, but I can bypass that. When we do our release we will want to ensure that we sign both the amd64 and arm64 binaries.

Done! :)

Is there anything I need to do about that here or just during the release?

For the release, the only thing here that will need updating is scripts/mac-signing.sh. We would need it to sign both files. Right now it is hard coded for darwin_amd64.tar only.

Now it is a loop that goes over both files.

/github/workspace/docs/NIGHTLIES.md:22:158 MD047/single-trailing-newline Files should end with a single newline character

The file looks better, but in the preview, the linux_armel.tar.gz file doesn't have a link.

The h from https was missing 🤦

For any reviewers, we are not merging this until after 1.21 goes out the door.
