docs: cross-link Nemotron-CC recipe as a production NeMo Curator example (#1767)

* docs: cross-link Nemotron-CC recipe as a production NeMo Curator example

Adds references to the Nemotron-CC data curation pipeline in README.md
and tutorials/README.md so users can discover a production-scale,
end-to-end example of NeMo Curator in use.

* docs: address review comments — add in-repo SDG link and complete pipeline stages

- Link to tutorials/synthetic/nemotron_cc/ alongside external recipe in both README.md and tutorials/README.md
- Expand Key Components to include language ID & filtering and all 7 pipeline stages per sarahyurick's feedback
- Add language identification step to the Real-World Recipe callout

+**Real-World Recipe:** The [Nemotron-CC curation pipeline](https://github.com/NVIDIA-NeMo/Nemotron/tree/main/src/nemotron/recipes/data_curation/nemotron-cc) uses NeMo Curator end-to-end — from Common Crawl extraction through language identification, exact/fuzzy/substring deduplication, ensemble quality classification, and LLM-based synthetic data generation — to reproduce the [Nemotron-CC datasets](https://huggingface.co/datasets/nvidia/Nemotron-CC-v2). The SDG stage is also available as an [in-repo tutorial](tutorials/synthetic/nemotron_cc/).
