Feature Request: Mermaid Diagram

[towfiq-rakin]

Hello, thank you for this project.

I've decided to shift from Quartz to Astro-erudite. One feature i'm missing is diagram generation using MermaidJS.

  ```mermaid
  sequenceDiagram
      Alice->>+John: Hello John, how are you?
      Alice->>+John: John, can you hear me?
      John-->>-Alice: Hi Alice, I can hear you!
      John-->>-Alice: I feel great!
``

this should be able to generate a diagram in blog.

sequenceDiagram
    Alice->>+John: Hello John, how are you?
    Alice->>+John: John, can you hear me?
    John-->>-Alice: Hi Alice, I can hear you!
    John-->>-Alice: I feel great!
