elvijs opened a new pull request #4603: [AIRFLOW-3717] Use DAG context managers in documentation examples
URL: https://github.com/apache/airflow/pull/4603
 
 
   ### Jira
   
   This PR addresses [AIRFLOW-3717](https://issues.apache.org/jira/browse/AIRFLOW-3717).
   
   ### Description
   
   This is a trivial refactor of the documentation examples to use the DAG context manager where appropriate.
   
   Note that my editor automatically removes unnecessary trailing whitespace, hope that's not a problem.
   
   ### Tests
   
   No additional tests have been added as it's documentation. I've built the docs locally and manually inspected the changes to ensure no fat-finger errors.
   
   ### Commits
   
   There's a single commit with the subject line referencing the JIRA issue.
   
   ### Documentation
   
   There's no new functionality, so no additional documentation has been added.
   
   ### Code Quality
   
   - [X] Passes `flake8`. Although strictly speaking, probably not necessary as no new code has been added.
