- Removed the document store configuration section and its associated rendering logic.
- Updated the embedder configuration to include dimension input for embedding models.
- Simplified the rendering of pipeline configurations and improved the selection process for LLM models.
- Enhanced the preview and generation functionality for configuration files.
