Expose metadata link to next version of the model

This PR adds a metadata field to link this model to a newer version of the same model family: Qwen/Qwen2.5-72B. This metadata field helps ensure people are using the latest version of your model.

If there are multiple version i.e. version 1, version 2 and version 3. Linking version 1 and 2, and 2 and 3 will mean the latest version is always shown. See https://huggingface.co/docs/hub/model-cards#specifying-a-new-version for more info.

Here is an example of what this looks like:
