This PR tweaks the HF integrations:
- `VoiceCraft` tag is lowercased to `voicecraft` => not a hard requirement but makes it more consistent with other libraries on the Hub.
- `voicecraft` is set as the `library_name` instead of simply a tag. This is better for taxonomy on the Hub.
Regarding the integration, I also opened https://github.com/huggingface/huggingface.js/pull/626 to make it more official on the Hub. In particular, there will now be an official `</> Use in VoiceCraft` button in all voicecraft models that display the code snippet to load the model. This should help users getting started with the model. It will also add a link to the voicecraft repo for the installation guide.
