[issue-1399] fix: update deprecation message for DataRow.get method

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.
