Nothing changes for release testers at this point.  The main goal here is
to get some post-commit testing so we can catch issues in the branch early.

Longer term I think have self-hosted runners would be great, because it would
allow us to fully automate the testing and uploading we do when a release gets
tagged.

You are correct that GitHub only provides x86 machines, however, they don't
have enough disk space (14GB) to be able to run the test-release.sh script, so
adding x86 self-hosted builders with more disk space would still be very useful.
