The `ascending()` function refines a `ItemsQueryBuilder` to sort by the value of `propertyName` in ascending order.
You can specify multiple properties for sorting in ascending order by passing each property name as an additional argument. `ascending()` sorts the results in the order the properties are passed.
You can sort the following types:
- Number: Sorts numerically.
- Date: Sorts by date and time.
- String: Sorts lexicographically, so `'abc'` comes after `'XYZ'`.
If a property contains a number stored as a string (for example, `'0'`), that value is sorted alphabetically and not numerically. If a property doesn't have a value, that value is ranked lowest.
