Add paper, project page, and code links

Hi! I'm Niels from the community science team at Hugging Face.

This pull request improves the dataset card for the Sphere Encoder FID artifacts by:
- Adding relevant metadata (task categories).
- Linking the research paper, project page, and official GitHub repository.
- Providing a sample usage snippet found in the GitHub repository to help users evaluate their models.
- Adding the BibTeX citation for the paper.

+## Sample Usage
+
+To evaluate a trained model using these artifacts, you can use the evaluation script provided in the [GitHub repository](https://github.com/facebookresearch/sphere-encoder):
+
+```bash
+./run.sh eval.py \
+  --job_dir sphere-base-base-cifar-10-32px \
+  --forward_steps 1 4 \
+  --report_fid rfid gfid \
