feat: Update model lists and enhance model retrieval in Adaptor

- Refactored ModelList in the gemini constant to include new models and remove outdated ones.
- Modified the GetModelList function in the Adaptor to consolidate model lists from multiple sources, ensuring a comprehensive and updated list is returned.
- Commented out deprecated models in the vertex constants for clarity and future reference.
