    fix(standalone): Remove hardcoded Webserver port (#20429)
    
    Port 8080 is the default port for webserver (https://airflow.apache.org/docs/apache-airflow/stable/cli-and-env-variables-ref.html?highlight=webserver#webserver). By setting it here again explicitly, we forbid users to override it using AIRFLOW__WEBSERVER__WEB_SERVER_PORT. Removing it IMO is not a breaking change, since it will still default to 8080.
    
    (cherry picked from commit 9d36b1fdac16d8db8907d4b792fdbe13a6e80f7e)

 Upon running these commands, Airflow will create the ``$AIRFLOW_HOME`` folder
 and create the "airflow.cfg" file with defaults that will get you going fast.
+You can override defaults using environment variables, see :doc:`/configurations-ref`.
 You can inspect the file either in ``$AIRFLOW_HOME/airflow.cfg``, or through the UI in
 the ``Admin->Configuration`` menu. The PID file for the webserver will be stored
 in ``$AIRFLOW_HOME/airflow-webserver.pid`` or in ``/run/airflow/webserver.pid``
