[improve] Unify the resource use in both yaml and Python API

[zhongjiajie]

in apache/dolphinscheduler#10911, we add new mechanisms for reading resource from other system, but in yaml define, we also have its own file resource syntax

dolphinscheduler-sdk-python/examples/yaml_define/Sagemaker.yaml

Lines 24 to 27 in 6cd9784

	tasks:
	- name: sagemaker
	task_type: Sagemaker
	sagemaker_request_json: $FILE{"example_sagemaker_params.json"}

and we should combine then into unify
