Consider GitHub Copilot Reviews

**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
@kou and others are working to optimize github copilot reviews in the main arrow repo, see
- https://github.com/apache/arrow/pull/50117

I think these reviews are valuable and could potentially help improve the throughput of reviews in this repo

**Describe the solution you'd like**
1. Enable Copilot reviews in arrow-rs

**Describe alternatives you've considered**

**Additional context**

Start by reviewing the referenced Apache Arrow pull request 50117 and the arrow-rs repository's GitHub settings. Confirm how Copilot reviews are enabled there, and consider the work done when Copilot reviews are enabled for arrow-rs.
