fix: issue with sorting by multiple columns in a table (#19920)

Recent commit to sort alphanumeric columns via case insensitive
comparison broke the multi-column sort option. React-table only sorts
by the second (or third...) column if the first column matches.
Since the alphanumeric sort only returned -1 or 1, it never would move
to the subsequent columns when the earlier column values matched.
