There seams to be an issue with the nightly builds, looks like a sync issue between the build-toolkit and build-os jobs. Just seen few times in nightly workflow which uses the same exact logic as the PR workflow.
Increasing the time between retries will not harm and hopefully give it a chance to ghcr.io to sync. With the change retries will span up to 2min before giving up.
