Allow deleting a subset/config from a no-script dataset

TODO:
- [x] Add docs
- [x] Delete token arg from CLI example
  - See: #6839

Close #6810.

Comments:
The docs for this PR live [here](https://moon-ci-docs.huggingface.co/docs/datasets/pr_6820). All of your documentation changes will be reflected on that endpoint. The docs are available until 30 days after the last update.

This is ready for review, @huggingface/datasets.

I am adding a test...

@lhoestq I am getting an error in the test and I think it happens because the CI endpoint does not have the /preupload functionality:
```
huggingface_hub.utils._errors.RepositoryNotFoundError: 401 Client Error. (Request ID: Root=1-662a4de9-7134df595e29e4c073ac1298;332ff6e3-597a-4dfc-89df-4e9ac64215ad)

Repository Not Found for url: https://hub-ci.huggingface.co/api/datasets/__DUMMY_TRANSFORMERS_USER__/test-dataset-6c54e2-17140484441915/preupload/main?create_pr=1.
Please make sure you specified the correct `repo_id` and `repo_type`.
If you are trying to access a private or gated repo, make sure you are authenticated.
Invalid username or password.
Note: Creating a commit assumes that the repo already exists on the Huggingface Hub. Please use `create_repo` if it's not the case.
```

@lhoestq, finally, I implemented the test with a mock of the call to `HfApi.create_commit`.
