Add Jupyter notebook tutorials for data classifiers

[sarahyurick]

In https://github.com/NVIDIA/NeMo-Curator/tree/main/tutorials/distributed_data_classification, we should:

• Split distributed_data_classification.ipynb into domain and quality notebooks
• Create multilingual domain classifier notebook
• Create FineWeb-Edu classifier notebook
• Create AEGIS classifier notebook
• Create Instruction-Data-Guard classifier notebook (depends on Add support for FineTune-Guard classifier #397)
• Create content type classifier notebook (depends on Content Type Classifier #361)
• Create prompt task and complexity classifier notebook (depends on Prompt Task/Complexity Classifier #364)

Then, we should link to each on their respective Hugging Face pages.
