fix: update mermaid diagram rendering in extra.js to use new API

- Refactored the mermaid rendering logic to utilize the latest API for generating diagrams.
- Improved error handling by displaying the error message directly instead of using a string property.
- Ensured that the diagram's HTML is updated correctly after rendering.
