Subject: [PATCH] github_packages: use exponential backoff when retrying

The retry behaviour in `publish_commit_bottles.yml` [1] is often
successful after the second try, so it's likely that we're not waiting
long enough in between retries here.

Let's fix that by retrying with exponential backoff instead of adding a
fixed interval of five seconds after each failure.
