backstage: HttpError: Not Found when publishing GitHub repo with scaffolder

Expected Behavior

No error

Current Behavior

GitHub API returns not found sometimes as it’s eventually consistent

Code here is bombing out: https://github.com/backstage/backstage/blob/master/plugins/scaffolder-backend/src/scaffolder/actions/builtin/publish/github.ts#L169-L186

Possible Solution

Thinking of either trying to retrieve from GitHub API or just adding in some retries

Steps to Reproduce

1. scaffold with a template that adds github teams
2. attempt a few times, I’ve had it happen to me 2 out of ~15 tries
3. …

Context

Other blocks in the GitHub publisher have try .. catch .. log but that’s a terrible pattern as the user will likely never see it. This needs proper hardening.
