Correctly handle new lines in CSV validation script

Attempting to fix Github Action errors found where the CSV file new lines are not interpreted correctly.

If newline='' is not specified, newlines embedded inside quoted fields will not be interpreted correctly, and on platforms that use \r\n linendings on write an extra \r will be added. It should always be safe to specify newline='', since the csv module does its own (universal) newline handling.

We see that in the Google spreadsheet, there are some values that have new lines values in them.
