Failed to download action - Error: Response status code does not indicate success: 401 (Unauthorized)

Describe the bug
We have been having problems the last 24 hours with downloading an action. It intermittently fails with a 401:

To Reproduce

Expected behavior
The action should be able to be downloaded as it is public.

Start with the action-download failure shown in the linked GitHub Actions job log and trace the request to the GitHub API tarball endpoint. Investigate why a public action intermittently receives HTTP 401 responses; done means reproducing or explaining the failure and confirming that public actions download successfully without unauthorized errors.
