Update dataset card for SpatialEdit-500K

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

This PR improves the dataset card for SpatialEdit-500K by:
- Adding `image-to-image` to the task categories in the YAML metadata.
- Linking the paper to its Hugging Face papers page.
- Adding a link to the GitHub repository.
- Including the citation information.

This helps in making the dataset more discoverable on the Hub.

 # SpatialEdit-500K
 
-SpatialEdit-500K is a synthetic training dataset for fine-grained image spatial editing. It is built for learning geometry-aware edits such as object moving, object rotation, camera viewpoint change.
+SpatialEdit-500K is a synthetic training dataset for fine-grained image spatial editing. It is built for learning geometry-aware edits such as object moving, object rotation, and camera viewpoint change.
 
-The dataset is released as part of the **SpatialEdit** project and is generated with a controllable rendering pipeline to provide structured spatial transformations at scale.
+The dataset was introduced in the paper [SpatialEdit: Benchmarking Fine-Grained Image Spatial Editing](https://huggingface.co/papers/2604.04911). It is generated with a controllable rendering pipeline to provide structured spatial transformations at scale.
 
-## Highlights
-
-- Large-scale synthetic data for spatially grounded image editing
-- Covers both object-centric and camera-centric transformations
-- Used to train the SpatialEdit baseline model
