ci: Add first native Linux ARM runners

Since there are native ARM runners available now, we should use them.
Let's test this.

This is the source: https://docs.github.com/en/actions/using-github-hosted-runners/using-github-hosted-runners/about-github-hosted-runners#standard-github-hosted-runners-for-public-repositories
As indicated, this is still in beta.
