Librarian Bot: Add base_model metadata to model

This pull request aims to enrich the metadata of your model by adding `base_model` metadata to `YAML` block of your model's `README.md`.

How did we find this information? We use the `mergekit_config.yml` config from [mergekit](https://github.com/cg123/mergekit).

**Why add this?** Enhancing your model's metadata in this way:
- **Boosts Discoverability** - It becomes straightforward to trace the relationships between various models on the Hugging Face Hub.
- **Highlights Impact** - It showcases the contributions and influences different models have within the community.

For a hands-on example of how such metadata can play a pivotal role in mapping model connections, take a look at [librarian-bots/base_model_explorer](https://huggingface.co/spaces/librarian-bots/base_model_explorer).
