Feature Request / Improvement

Inspired by https://github.com/apache/iceberg-python/pull/3098, which documents mapping between pyarrow and pyiceberg types

Think its useful to document Iceberg Type <> Arrow type?

Maybe just put this into writing https://github.com/apache/iceberg/blob/c9f6c8423be7cbf52c9cf678896deca478b3b6d1/arrow/src/main/java/org/apache/iceberg/arrow/ArrowSchemaUtil.java#L68-L192
