Greptile Summary

This PR adds a documentation page and code snippet for the dagster-hf-datasets community integration, which connects Dagster with Hugging Face Datasets for loading, transforming, and publishing datasets.

• New docs page (docs/docs/integrations/libraries/datasets/index.md) describes installation, capabilities, and links to a pipeline example; the CodeExample path and test-exclusion entry are correctly set after addressing prior review comments.
• Pipeline snippet (dataset_pipeline_example.py) demonstrates a full multi-asset pipeline: loading the GLUE QQP dataset, deduplication, filtering, normalization, and publishing back to the Hub via HFDatasetPublisher.

Confidence Score: 5/5

Documentation-only change with a companion snippet; no runtime Dagster code paths are modified.

All changed files are docs, a static image, and a test exclusion list. The pipeline snippet is well-structured, MaterializeResult(value=...) is a valid Dagster API, and the test exclusion path correctly includes the hf_datasets/ subdirectory so CI won't attempt to import the snippet without the library installed.

No files require special attention.

Important Files Changed

Filename	Overview
docs/docs/integrations/libraries/datasets/index.md	New docs page for hf-datasets integration; CodeExample path and slug are correct; minor: pypi URL uses underscores while the rest of the codebase consistently uses hyphens.
examples/docs_snippets/docs_snippets/integrations/hf_datasets/dataset_pipeline_example.py	End-to-end pipeline example covering load, dedup, filter, normalize, and publish stages; MaterializeResult(value=...) usage is valid; all assets are wired into Definitions.
examples/docs_snippets/docs_snippets_tests/test_integration_files_load.py	Adds hf_datasets/dataset_pipeline_example.py to EXCLUDED_FILES with the correct subdirectory path, preventing CI failures when dagster-hf-datasets is not installed.
docs/static/images/integrations/hf_datasets.svg	New SVG logo for the HF Datasets integration sidebar; referenced correctly by the docs page frontmatter.
