1. Is this request related to a challenge you're experiencing? Tell me about your story.

If i create a dataset by api, it can not be used directly，it must be added in knowledge retrieval node manually.
But i have got the info of dataset by api, so i want to run a workflow with the datasetId.
I commit a pr(#14261) to achieve this feature
