Pull Request Overview

This PR updates the return types of two protected methods in the Document class to support asynchronous operations by changing from Optional<Date> to MaybePromise<Optional<Date>>. This is a non-breaking change that allows these methods to optionally return promises while maintaining backward compatibility.

• Updated getDisplayDate() and getPublicationDate() method signatures to support both synchronous and asynchronous operations
• Incremented package version from 4.43.1 to 4.43.2
• Added changelog entry documenting the MaybePromise enhancement
