Docusaurus maintainer here

I agree the md editing story for non-dev contributor is not great.

You can try a git based CMS like Tina, they have a Docusaurus starter/example.

StackBlitz web publisher is also a good solution, allowing you to run Docusaurus directly in the browser in a very simple interface allowing you to commit or send PRs easily. No need to install nodejs locally, and you get a real preview.
