Summary of Changes

Hello @damccorm, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a minor formatting inconsistency and enhances an existing entry in the CHANGES.md file. The primary goal is to improve the readability and accuracy of the project's change history by correcting a whitespace issue and adding more descriptive detail to a previous change regarding deprecated Hadoop versions for IcebergIO.

Highlights

• Whitespace Correction: A minor whitespace issue was resolved in the CHANGES.md file, specifically within an entry detailing the removal of deprecated Hadoop versions for Iceberg.
• Changelog Enhancement: The same changelog entry was updated to provide more specific context by adding "from IcebergIO" and linking to the relevant pull request (#36282).
