Improve model card: Add pipeline tag, paper, project page, and code links

This PR improves the model card by:

- Setting the `pipeline_tag` to `text-generation`, ensuring the model can be found under the correct pipeline on the Hugging Face Hub.
- Adding a prominent link to the paper: [Reasoning Vectors: Transferring Chain-of-Thought Capabilities via Task Arithmetic](https://arxiv.org/abs/2509.01363).
- Including a link to the project page: https://elm.baulab.info.
- Adding a link to the GitHub repository: https://github.com/rohitgandikota/erasing-llm.

These additions make the model card more informative and improve discoverability.

-This is a merge of pre-trained language models created using [mergekit](https://github.com/cg123/mergekit).
+This repository hosts a merged language model, based on the work presented in [Reasoning Vectors: Transferring Chain-of-Thought Capabilities via Task Arithmetic](https://arxiv.org/abs/2509.01363). This work demonstrates that reasoning ability, once learned, can be extracted and transferred between models as a compact task vector, offering a practical way to enhance models by recycling prior computational investments.
