This PR enhances the model card by:
- Adding `pipeline_tag: unconditional-image-generation` for better discoverability of the model's functionality.
- Specifying `library_name: transformers` to enable the "how to use" widget, as demonstrated by the provided inference code in the official GitHub repository.
- Including a link to the project website: `https://imagination-research.github.io/distilled-decoding`.
- Adding a "Sample Usage" section directly from the official GitHub repository for clear, actionable instructions on how to get started with the model.
