Disable cron job running on forked repo

[ejguan]

🐛 Describe the bug

My forked repo of torchdata have been running the cron job to validate nightly binaries.

See workflow https://github.com/ejguan/data/actions/runs/4097726223

@atalman Is this expected? Can we disable it by doing something like: https://github.com/pytorch/data/blob/01fc76200354501b057bb439b43a1f05f609dd0a/.github/workflows/nightly_release.yml#L11
