Closes https://github.com/zed-industries/zed/issues/10696

Adds support for rendering Mermaid diagrams in the markdown preview
using

(with [a
patch](https://github.com/1jehuang/mermaid-rs-renderer/pull/35)).

- Shows the previously cached image while re-computing
- Supports a scale parameter i.e. default 100
