This PR enhances the `InfraDepth` dataset card by:
- Adding the `task_categories` metadata (`depth-estimation`).
- Including relevant `tags` such as `3d-point-cloud`, `image-restoration`, `image-segmentation`, and `civil-engineering` for improved discoverability.
- Providing a direct link to the paper ([https://huggingface.co/papers/2509.03324](https://huggingface.co/papers/2509.03324)).
- Adding a link to the official GitHub repository for the associated code ([https://github.com/Jingyixiong/InfraDiffusion-official-implement](https://github.com/Jingyixiong/InfraDiffusion-official-implement)).
- Incorporating a "Sample Usage" section with code snippets from the GitHub README, demonstrating how to run InfraDiffusion using the dataset.
- Populating the "Citation" section with the full BibTeX entry from the paper.
These changes will make the dataset more discoverable and easier to use for the community.
