feat(index.html): add Vertex AI credential import UI

- Implemented the UI for importing Vertex AI credentials, including file selection and input fields for location and JSON key.
- Enhanced internationalization support with appropriate labels and hints in both English and Chinese.
- Removed the previous implementation of the Vertex AI credential import section to streamline the code.
