Improve model card with library name and GitHub link

This PR improves the model card by adding the `library_name: transformers` metadata, clarifying the model's compatibility with the Hugging Face `transformers` library. It also includes a link to the GitHub repository containing the LongRoPE code. This enhances the model card's completeness and user-friendliness.

+# LongRoPE2: Near-Lossless LLM Context Window Scaling
+
+The model was presented in the paper [LongRoPE2: Near-Lossless LLM Context Window Scaling](https://hf.co/papers/2502.20082).
+
+# Paper abstract
+
+The abstract of the paper is the following:
+
+LongRoPE2 is a novel approach that extends the effective context window of pre-trained large language models (LLMs) to the target length, while preserving the performance on the original shorter context window. This is achieved by three contributions: (1) a hypothesis that insufficient training in higher RoPE dimensions contributes to the persistent out-of-distribution (OOD) issues observed in existing methods; (2) an effective RoPE rescaling algorithm that adopts evolutionary search guided by "needle-driven" perplexity to address the insufficient training problem; (3) a mixed context window training approach that fine-tunes model weights to adopt rescaled RoPE for long-context sequences while preserving the short-context performance with the original RoPE. Extensive experiments on LLaMA3-8B and Phi3-mini-3.8B across various benchmarks validate the hypothesis and demonstrate the effectiveness of LongRoPE2. Remarkably, LongRoPE2 extends LLaMA3-8B to achieve a 128K effective context length while retaining over 98.5% of short-context performance, using only 10B tokens -- 80x fewer than Meta's approach, which fails to reach the target effective context length. Code will be available at https://github.com/microsoft/LongRoPE.
