Probably want someone more familiar with API to make sure.

I think the list is in order from oldest run to newest run.

Specifically saw an issue when merging Homebrew/homebrew-core#121077, which had 2 runs due to dropping a commit. The wrong bottles.zip was uploaded Homebrew/homebrew-core@0eac664

---

Similar issue in Homebrew/homebrew-core#116350. Due to PR getting closed and re-opened, there were 2 runs. The 1st run with only a single bottle got uploaded Homebrew/homebrew-core@0896128 rather than 2nd run with all bottles.

      query ($user: String!, $repo: String!, $pr: Int!) {
        repository(owner: $user, name: $repo) {
