Adding other processing steps
Previously, `split-duckdb-index` was triggered only by `config-split-names-from-info` but when this step finished with error 500 because of ResponseAlreadyComputedError, `split-duckdb-index` never started.
Adding other parents to avoid skipping job compute. 

Note that  the issue with parallel processing steps will remain and should be fixed on https://github.com/huggingface/datasets-server/issues/1358
