feat(mm): revised starter models

[psychedelicious]

Summary

Revised the list of starter models, made a small change to how it's structured.

• Enriched dependencies to not just be a string - allows reuse of a dependency as a starter model and dependency of another model. For example, all the SDXL models have the fp16 VAE as a dependency, but you can also download it on its own.
• Looked at popular models on the major model sites to select the list. No SD2 models. All hosted on HF.
