• 🔗 Issue: Fixes: row[columnAccessor] is deprecated but commonly used in perRowCol #1353
• ⚙️ Trigger: Issue

📊 Junie Summary\nThe deprecation message for DataRow.get(ColumnReference) was updated to inform users about switching to col[row], especially in the context of perRowCol. The code changes were successfully implemented, but the project build failed due to an external dependency issue unrelated to the code updates.

@jetbrains-junie Great job! Though, it's not necessary to mention perRowCol or the url in the deprecation message. Simply mentioning that col[row] is still available is enough

✅ The execution was successful

The deprecation message for DataRow.get(ColumnReference) was successfully updated to simplify its content, specifically removing mentions of perRowCol and a URL, while retaining that col[row] is still available. However, the project build failed due to an external dependency issue unrelated to the code changes.
