Problem

The review team wants product ratings tiered inside each category with no gaps on ties. Within each category, rank products by rating with the highest rating at position 1; tied ratings share a position, and the next rating down takes the immediately following position. Skip products with no rating. Return the product_name, category, rating, and position.
