feat: add Voyage AI embedder support

[nubol23]

Context

Added support for Voyage AI as an embedding provider for code indexing. They provide a specialized code model and cheap contextual embedding ones with good parallelization for faster ingestion.

Implementation

• New Embedder: Created src/services/code-index/embedders/voyage.ts to implement the IEmbedder interface for the Voyage API.
• Service Factory: Updated CodeIndexServiceFactory to handle initialization and validation of the Voyage embedder.
• Configuration: Added VoyageOptions to the global configuration types to store the API key.
• UI: Updated CodeIndexPopover.tsx to include Voyage in the provider dropdown and allow users to input their API key.
• Testing: Added unit tests in service-factory.spec.ts.
