Using the table playground.product_transactions, write a query to find the top 3 pairs of products that are most frequently bought together in the same transaction from the table playground.product_transactions. For this analysis, consider a pair to consist of two different products purchased in the same transaction. The output should list the pairs of products and the frequency of each pair (product1, product2, freq), ordered by product1 in ascending order, product2 in ascending order and frequency in descending order.

• transaction_id int
