Allow sorting by specified field for Document Tree macro

At the moment, Document Tree macro allows users to display a tree of documents with the titles and sort the documents alphabetically. To make the macro more flexible and enhance its functionality, a new feature might be introduced that allows users to sort documents based on various document properties. Specifically with a new parameter sortBy{property}="true", where property can be replaced with the desired document property, such as creation date, author's name, or any other property.
