"This endpoint is temporarily being throttled" should be handled specially

[jsoref]

During https://www.githubstatus.com/incidents/7ylfn6fnwgrq, I had a job that tripped on:

Error: Get Pages site failed. Please verify that the repository has Pages enabled and configured to build using GitHub Actions, or consider exploring the enablement parameter for this action. Error: This endpoint is temporarily being throttled. Please try again later. For more on scraping GitHub and how it may affect your rights, please review our Terms of Service (https://docs.github.com/en/site-policy/github-terms/github-terms-of-service) - https://docs.github.com/rest/using-the-rest-api/rate-limits-for-the-rest-api
Error: HttpError: This endpoint is temporarily being throttled. Please try again later.

This advice doesn't make sense in this circumstance:

Please verify that the repository has Pages enabled and configured to build using GitHub Actions, or consider exploring the enablement parameter for this action.
