[PR] Add round-robin reviewer auto-assignment [sedona-db]

jiayuasu opened a new pull request, #720:
URL: https://github.com/apache/sedona-db/pull/720

   Automatically assigns one reviewer per PR in round-robin from the list in `.github/reviewers.json`.
   
   **How it works:**
   - `assign-reviewer.yml` (triggered by `pull_request`) captures PR number and author into an artifact
   - `assign-reviewer-write.yml` (triggered by `workflow_run`) reads the artifact, loads the reviewer list from the trusted `main` branch, computes the round-robin pick, and assigns the reviewer
   
   This follows the ASF-recommended `pull_request` + `workflow_run` split pattern to safely handle fork PRs without using `pull_request_target`. See [ASF GitHub Actions Security](https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=321719166).
   
   **To update the reviewer list**, edit `.github/reviewers.json` — no workflow changes needed.

Review Comment:
   The PR metadata artifact will use the default retention period, which is typically much longer than needed for a short-lived `workflow_run` handoff. Consider setting a small `retention-days` (e.g., 1–7) to reduce artifact storage and clutter.

Review Comment:
   `repository: apache/sedona-db` hard-codes the repo name for the trusted checkout. This will break if the repo is renamed or if the workflow is run in a fork; consider using `${{ github.repository }}` (and still pinning `ref: main`) to keep the workflow self-contained and maintainable.

Review Comment:
   The round-robin index is off by one: using `prNumber % eligible.length` will select `eligible[1]` for PR #1 (skipping the first reviewer). If the intent is to start with the first reviewer for PR #1, compute the index from a 0-based PR sequence (e.g., `prNumber - 1`).
