Publish packages for Linux ARM64

[tibdex]

This is required to be able to install this package in a Docker image built on macOS with Apple Silicon without having to resort to the --platform=linux/am64 option slowing the container execution.

See https://pythonspeed.com/articles/docker-build-problems-mac.

Depends on https://github.com/actions/runner-images/issues/5631 since relying on self-hosted runners makes testing and publishing more cumbersome.
