Update model card with Primus paper link and image-segmentation tag

This PR updates the model card to include a link to the [Primus paper](https://huggingface.co/papers/2503.01835), which introduces the Transformer-centric architectures used for these checkpoints. Additionally, the `pipeline_tag` has been updated to `image-segmentation` to better reflect the intended downstream use case in medical imaging. Relevant citations for both the OpenMind benchmark and the Primus paper have also been added.

 ## Overview

-📄 **An OpenMind for 3D medical vision self-supervised learning** (Wald, T., Ulrich, C., Suprijadi, J., Ziegler, S., Nohel, M., Peretzke, R., ... & Maier-Hein, K. H. (2024).)  
-([arXiv:2412.17041](https://arxiv.org/abs/2412.17041)) — the first extensive benchmark study for **self-supervised learning (SSL)** on **3D medical imaging** data.
+This repository provides self-supervised pre-trained weights for 3D medical image analysis. These models were pre-trained on the [OpenMind Dataset](https://huggingface.co/datasets/AnonRes/OpenMind), a large-scale collection of brain MRI data.
 
-Each model was pre-trained using a particular SSL method on the [OpenMind Dataset](https://huggingface.co/datasets/AnonRes/OpenMind), a large-scale, standardized collection of public brain MRI datasets.
+**Primus** and **PrimusV2** are Transformer-centric segmentation architectures designed to maximize the effectiveness of attention mechanisms in 3D medical imaging. By moving away from heavy convolutional reliance, Primus achieves state-of-the-art results on several benchmarks.
 
-**These models are not recommended to be used as-is for feature extraction.** Instead we recommend using the downstream fine-tuning frameworks for **segmentation** and **classification** adaptation, available in the [adaptation repository](https://github.com/TaWald/nnUNet).
-*While manual download is possible, we recommend using the auto-download feature of the fine-tuning repository by providing the repository URL on Hugging Face instead of a local checkpoint path.*
