Render mermaid embedded within swagger/openapi

[grahamegee]

I've installed the mermaid plugin for docusaurus and it renders just fine when I use a mermaid code block within a doc, but it doesn't when I embed mermaid within my swagger.json.

I found This Issue on the redoc repo which suggests a work around. I was wondering if there was an equivalent workaround that would work for recodusaurus?
