commit decc3bdd9c854dec5715eedd52af9ea47f17df77

Fix Slack notifier howto guide code example for Airflow 3 (#66111)
* Fix Slack notifier howto guide code example for Airflow 3
Add missing required dag_id parameter, schedule=None, and catchup=False
to the DAG constructor in the code snippet. Without dag_id the example
raises a TypeError at parse time.
* Use airflow.sdk import for DAG in Slack notifier howto guide
from airflow import DAG is a legacy shim; Airflow 3 DAG authoring
code should use from airflow.sdk import DAG.
