Add task category, paper and project page links

This PR improves the dataset card by adding:
- `task_categories: ['image-to-3d']` in the metadata to enhance discoverability.
- A link to the paper ([MORE: Multi-Organ Medical Image REconstruction Dataset](https://huggingface.co/papers/2510.26759)) for easy access to the research.
- A link to the project page (https://more-med.github.io/) for additional information.
- A brief description of the dataset's scope and purpose, extracted from the paper abstract.
