Update example DAG files to latest syntax

[mik-laj]

Hello,

When we stop releasing backport packages, we will be able to update all example DAGs to use the new syntax for handling outputs introduced by AIP-31.

This is an example change.

 product_set_update = CloudVisionUpdateProductSetOperator(
     location=GCP_VISION_LOCATION,
-    product_set_id="{{ task_instance.xcom_pull('product_set_create') }}",
+    product_set_id=product_set_create.output,
     product_set=ProductSet(display_name='My Product Set 2'), 
    task_id='product_set_update',
)

Best regards,
Kamil Bregułła

Or Maybe we can do automated refactoring for that one ? Sounds doable.

This should be probably part of #9041

Hey, I am new here :). Can I contribute on this issue as my first contribution? Has someone already addressed this issue?

@hsnprsd feel free to take this one 🚀 I'm happy to help with eventual questions. I think, as a good start we should refactor airflow/example_dags/* to use .output instead of jinja whenever it is possible (those DAGs are not part of providers).
