Release arrow-rs / parquet Patch version 57.3.1 (May 2026) #9858

• Part of [EPIC] A collection of release tickets #7392
• Follow on to Release arrow-rs / parquet Minor version 57.3.0 (January 2026) #9240

There have been several overflow fixes recently that I think are important enough to warrant a minor patch release to increase the security posture of arrow-rs. The most recent 57 line release was Jan 2026, 6 months ago, so I believe it would be good to release a minor release with overflow protection for those users still upgrading.
