Add pipeline tag and paper link

Hi! I'm Niels from the Hugging Face community science team. I noticed this repository was missing a `pipeline_tag` and a direct link to its corresponding paper. This PR adds the `image-to-3d` tag to improve visibility on the Hub and links the Markdown content to the research paper page. I've also included the citation information from the official repository.

+Geometric Latent Diffusion (GLD) is a framework that repurposes the geometrically consistent feature space of geometric foundation models (such as Depth Anything 3 and VGGT) as the latent space for multi-view diffusion. By operating in this space rather than a view-independent VAE latent space, GLD achieves consistent novel view synthesis (NVS) and 3D reconstruction with significantly faster training convergence.
 
 ## Quick Start
 
+To use these models, follow the setup instructions in the [official GitHub repository](https://github.com/cvlab-kaist/GLD).
