Add CC Index URL list tutorial

[VibhuJawa]

Summary

• add a YAML-driven tutorial for building a global unique URL list from selected Common Crawl Index snapshots on PBSS
• run Curator ExactDeduplicationWorkflow(text_field="url", assign_id=True) directly on the configured CC Index parquet inputs
• run TextDuplicatesRemovalWorkflow(input_fields=["url", "warc_filename"], output_fields=["url", "warc_filename"]) on the same inputs to write global_unique_urls/
• link the tutorial from the text tutorials index

Validation

• git diff --check
• uv run --group linting ruff check tutorials/text/cc-index-url-list/create_cc_index_url_list.py
• python -m py_compile tutorials/text/cc-index-url-list/create_cc_index_url_list.py
• PBSS dry-run/listing smoke with --max-files-per-crawl 1 --dry-run

Notes

• The full PBSS exact-dedup run is documented but not executed here because this login node has no usable NVIDIA driver and no cudf install.
• included_crawls is authoritative; excluded crawls are omitted from the YAML rather than represented as a separate config field.
