Add arXiv metadata and update citation with paper links

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

This PR improves the model card for GLM-5 by:
- Adding the `arxiv` tag to the metadata to link the repository with its technical report.
- Adding direct links to the paper and the official GitHub repository at the top of the description.
- Updating the citation section with the correct BibTeX entry.

These changes help researchers and developers easily access the associated technical documentation and codebase.

 ## Introduction
 
 We are launching GLM-5, targeting complex systems engineering and long-horizon agentic tasks. Scaling is still one of the most important ways to improve the intelligence efficiency of Artificial General Intelligence (AGI). Compared to GLM-4.5, GLM-5 scales from 355B parameters (32B active) to 744B parameters (40B active), and increases pre-training data from 23T to 28.5T tokens. GLM-5 also integrates DeepSeek Sparse Attention (DSA), largely reducing deployment cost while preserving long-context capacity.
