🐛 fix(Item Update): Fix `ItemUpdateSchema` by adding `store_id`

+Our `ItemUpdateSchema` at the moment looks like this:
+
+```python title="schemas.py"
+class ItemUpdateSchema(Schema):
+    name = fields.Str()
+    price = fields.Float()
+```
+
+But since now our update endpoint may create items, we need to change the schema to optionally accept a `store_id`.
+
+When updating an item, `name` or `price` (or both) may be passed, but when creating an item, `name`, `price`, and `store_id` must be passed.
+
+Update the `ItemUpdateSchema` to this:
+
+```python title="schemas.py"
+class ItemUpdateSchema(Schema):
+    name = fields.Str()
+    price = fields.Float()
+    store_id = fields.Int()
+```
