Run Apache Airflow DAG and Retrieve XCom Value

What this workflow does

This workflow integrates the Apache Airflow API [DAGRun](https://airflow.apache.org/docs/apache-airflow/2.10.5/stable-rest-api-ref.htmltag/DAGRun) and [XCom](https://airflow.apache.org/docs/apache-airflow/2.10.5/stable-rest-api-ref.htmltag/XCom). It enables n8n to trigger Airflow DAGs and retrieve the execution results.

1. Update Airflow API Link Prefix

- Navigate to the airflow-api node. - Update the prefix of the Airflow API link in the format: http(s)://ip:port. - Example: https://airflow.example.com

2. Configure Authentication
