Hi, I'm Niels from the Hugging Face community science team. This PR improves the model card for EmbeddingRWKV by:
- Adding the `text-retrieval` pipeline tag for better discoverability.
- Linking the research paper: [EmbeddingRWKV: State-Centric Retrieval with Reusable States](https://huggingface.co/papers/2601.07861).
- Linking the official [GitHub repository](https://github.com/howard-hou/EmbeddingRWKV).
- Updating usage snippets to match the code found in the project's repository.
