The SQL Server Data Row Size Question: Why Is It Bigger?

This morning, I received the following question from a user:
Could you please clarify SQLServer “Data Row” size: If I run the script below on SQL Server 2012, then Slot(row) Size is 710 bytes if I run the same script against SQL Server 2016 and above, then Slot(row) Size is 724 bytes.
They then provided a script which creates and inserts a few rows into a sample table, runs the DBCC IND command to find a list of pages for the sample table, then uses the DBCC PAGE command to examine the page.
