Fix Changelog Entries for Data Lake Features

Summary

This PR cleans up several placeholder entries in the CHANGELOG.md file by:

1. Providing proper documentation for the Iceberg and DeltaLake custom disk configuration feature
2. Correcting setting names for Iceberg data file limits from max_iceberg_data_file_rows/bytes to iceberg_insert_max_rows_in_data_file/iceberg_insert_max_bytes_in_data_file
3. Removing placeholder markers (��WTF, fix this!) from the changelog entries

Changes

• Updated description for custom disk configuration in Iceberg and DeltaLake tables to specify that it's controlled via the disk storage level setting
• Fixed settings names for the Iceberg data file limits to match the actual implementation

Motivation
