AIP-72: Remove redundant handling of AirflowException

[kaxil]

This is already handled in the code below:

airflow/task_sdk/src/airflow/sdk/execution_time/task_runner.py

Lines 485 to 492 in 9de80ab

	except (AirflowTaskTimeout, AirflowException):
	# We should allow retries if the task has defined it.
	log.exception("Task failed with exception")
	msg = TaskState(
	state=TerminalTIState.FAILED,
	end_date=datetime.now(tz=timezone.utc),
	)
	# TODO: Run task failure callbacks here

So it will never reach

airflow/task_sdk/src/airflow/sdk/execution_time/task_runner.py

Lines 493 to 499 in 9de80ab

	except AirflowException:
	# TODO: handle the case of up_for_retry here
	log.exception("Task failed with exception")
	msg = TaskState(
	state=TerminalTIState.FAILED,
	end_date=datetime.now(tz=timezone.utc),
	)
