This pull request introduces a new feature to optionally emit dataset URIs as XCom values in Cosmos, along with comprehensive documentation and tests. The feature is controlled by a new configuration setting and is designed to help users access dataset URIs in downstream Airflow tasks when needed.
The most important changes are:
