List the titles of books with no translator recorded, oldest first. Include the release year so that an unknown translator is not confused with an old book.
Expected: 4 rows. They are The Enlightenment of the Greengage Tree (2019), Untranslated Orphan (2019), The Employees (2020), and The Seven Moons of Maali Almeida (2022). A comparison with NULL should not turn the unknown value into an ordinary string.
