When using authenticated requests, GitHub poses a limitation of 1000 API calls per hour. For buckets that have many GitHub-dependent manifests, this will be a problem.

Describe the solution you'd like

If the checkver utility is allowed to work on a set of app names, we can split the update process by passing each subset at a different hour so that we remain under the limit.

Describe alternatives you've considered

• checkver can currently work on a single app, or an entire folder. Neither is feasible because passing individual app names at each workflow run would be too wasteful.
• We can't pause based on the X-RateLimit-* HTTP headers, because we will have pause for an hour every time, which is not very ideal. It's better to just have separate workflow runs each time.

Note that this is not essential at the moment, because the largest known bucket as of now (Extras) seems to be doing just fine.

If the number of manifests reaches around 2000, this might be needed.
