Hopefully you got several cups of tea/coffee within the last 4 days ;-)

Just put the QUALIFY into a Derived Table:

     UPDATE TEA_MAKING
     FROM
       (
        SELECT * FROM TEA_MADE
           QUALIFY ROW_NUMBER() OVER (PARTITION BY TEA_MADE.MAKER_NM
           ORDER BY TEA_MADE.INCLUDE_COFFEE_IN, TEA_MADE.MADE_QT DESC) = 1
       ) AS TEA_MADE
     SET
        MADE_QT = TEA_MADE.MADE_QT,
        INCLUDE_COFFEE_IN=TEA_MADE.INCLUDE_COFFEE_IN
     WHERE
        TEA_MAKING.MAKER_NM=TEA_MADE.MAKER_NM
     ;
