Librarian Bot: Add merge tag to model

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

How did we find this information? We infered that this model is a `merge` model based on the presence of one of the following files:

- `merge.yml`
- `merge.yaml`
- `mergekit_config.yml`
- `mergekit_config.yaml`


**Why add this?** Enhancing your model's metadata in this way:
- **Boosts Discoverability** - It becomes easier to find merge models on the Hub
- **Helping understand the ecosystem** - It becomes easier to understand the ecosystem of merge models on the Hub
