[editor] Support erDiagrams

[lightningRalf]

Describe the bug
erDiagram that shows a preview, but no way to live edit.

To Reproduce
So I tried it:

title: "ART"

erDiagram
LLM ||--o{ ART : "is enhanced by"
FEWSHOT-ZEROSHOT ||--o{ ART : "is improved by"
COT ||--o{ ART : "is generated by"
TOOLS ||--o{ ART : "is selected and integrated by"
TASKLIBRARY ||--|{ ART : "is used by"
PERFORMANCE ||--|| ART : "is improved by"
PERFORMANCE }o--|| TASKS : "is measured on"

It shows the preview, but I cannot live edit my version.
Will this be developed? or am I doing something wrong?

Expected behavior
I can push a button, or see it directly in the live edit view on the main frame
