Improve model card with pipeline tag, library name, and project page link

This PR improves the model card by:

- Adding the `pipeline_tag: text-to-3d` to improve searchability on the Hugging Face Hub.
- Specifying the `library_name: diffusers`.
- Ensuring a clear link to the project page is present.

 ## Introduction
 While generative artificial intelligence has advanced significantly across text, image, audio, and video domains, 3D generation remains comparatively underdeveloped due to fundamental challenges such as data scarcity, algorithmic limitations, and ecosystem fragmentation.
