Improve model card metadata and add license

This PR improves the model card by:

- Adding the `library_name` to specify that the model is compatible with the `sentence-transformers` library.
- Ensuring the correct `pipeline_tag` is present for searchability.
- Adding an Apache 2.0 license.

This ensures the model is correctly categorized and discoverable on the Hugging Face Hub.
