Add paper link, project page, and improve metadata

Hi! I'm Niels from the Hugging Face community science team. I'm opening this PR to improve the dataset card for the CelloCut Benchmark.

Key changes:
- Added `task_categories: other` to the YAML metadata.
- Included links to the [paper](https://huggingface.co/papers/2605.17853), [GitHub repository](https://github.com/rangeryx-66/CelloCut), and [project page](https://rangeryx-66.github.io/CelloCut/).
- Updated the citation section with the official BibTeX from the paper.

These updates help ensure the dataset is properly documented and easier for the community to find and attribute.
