Fix missing back_populates in Note.item relationship in example code (#12925)

Without back_populates, the subsequent code would not automatically populate Item.notes or generate the key, which contradicts what the documentation intends to demonstrate.

(cherry picked from commit 1220858a0c5e85d4600b249dc3ae9412e01608ad)
