[CI] Move M1 self-hosted runners to newly available GitHub M1 runners

[raulcd]

Describe the enhancement requested

GitHub added availability of macOS ARM (M1) runners a couple of weeks ago for Open Source projects:
https://github.blog/changelog/2024-01-30-github-actions-introducing-the-new-m1-macos-runner-available-to-open-source/

It would be good to migrate our self-hosted M1 runners to ephemeral GitHub runners.
