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

in https://github.com/apache/dolphinscheduler/issues/10911, we add new mechanisms for reading resource from other system, but in yaml define, we also have its own file resource syntax

https://github.com/apache/dolphinscheduler-sdk-python/blob/6cd9784534eb3c78dbbf0daf53bf457a597fe3be/examples/yaml_define/Sagemaker.yaml#L24-L27

and we should combine then into unify

Start by reading the resource mechanisms referenced in issue #10911 and the resource syntax in examples/yaml_define/Sagemaker.yaml at lines 24-27. Compare how resources are represented in the YAML definition and Python API, then define completion as both interfaces using one consistent resource mechanism.
