The "view source" links in docs/apache_airflow seem fine, for example the example_kubernetes_executor link is ok here:

https://airflow.apache.org/docs/apache-airflow/stable/executor/kubernetes.html

but the "source" links for provider example dags are broken. For example, if you click on the "source" link for example_gcs_to_bigquery here, it directs you to https://airflow.apache.org/docs/apache-airflow-providers-google/stable/_modules/airflow/providers/google/cloud/example_dags/example_gcs_to_bigquery.html which is a 404. The same is true for the example_athena link here.
