What happened

airflow upgrade_check should check python_callable is not used in TriggerDagRunOperator.
As of #6317, python_callable is no longer supported (in any 2.x version) and dag tasks using it will fail to parse.
This is not currently verified by upgrade_check and I caught it only after upgrading to 2.x.

What you expected to happen

upgrade_check to verify parameters of TriggerDagRunOperator and warn that upgrade_check should be removed and replaced with passing conf dictionary directly.

How to reproduce

run airflow upgrade_check on a dag with the following task (from PR):

def _trigger_task(context, object):
    object.payload = {"message": "Hello world"}
    return object

trigger_task = TriggerDagRunOperator(
    task_id='test_trigger_dagrun',
    trigger_dag_id="example_trigger_target_dag",
    python_callable=_trigger_task,
    dag=dag,
)

Closing for two reasons:

1. There are no further releases of upgrade check tool as 1.10 is EOL.
2. In any case this is not something that can be added to the upgrade check as the conf param doesn't exist in TriggerDagRunOperator of 1.10 - It wasn't backported so this specific change is a breaking change. The upgrade checker will not suggest changes that results in broken dags on 1.10
