What's left in refactoring of processing steps and endpoints
Here I want to summarize once again the final changes that we need to make datasets-server consistent in naming and logic, see https://github.com/huggingface/datasets-server/issues/867 (because it's all scattered in comments to different issues)

## Rename steps

- [x] `/split-names-from-streaming` -> `config-split-names-from-streaming` https://github.com/huggingface/datasets-server/pull/1168
- [x] `/split-names-from-dataset-info` -> `config-split-names-from-info` https://github.com/huggingface/datasets-server/pull/1226
- [x] `/config-names` -> `dataset-config-names` https://github.com/huggingface/datasets-server/pull/1246

## Delete steps

- [x] `parquet-and-dataset-info` https://github.com/huggingface/datasets-server/pull/1043
- [x] `dataset-split-names-from-streaming` https://github.com/huggingface/datasets-server/pull/1106
- [x] `dataset-split-names-from-dataset-info` https://github.com/huggingface/datasets-server/pull/1141

## Endpoints
- [x] `/dataset-info` -> `/info` https://github.com/huggingface/datasets-server/pull/1468
- [x] delete `/parquet-and-dataset-info` https://github.com/huggingface/datasets-server/pull/1488
- [x] delete `/config-names`

## Misc
- [x] update the docs 
- [x] update the OpenAPI spec.
