Remove over 1500+ dependencies from the published package

Is your feature request related to a problem? Please describe
I'm always frustrated when I have to run storybook locally or when I have to deploy something with it. In the end it's a simple MDX to html transpiler and some fancy add-ons like knobs which require JS runtime (I suspect it's React, which makes my eyes bleed when I read your error messages).

Describe the solution you'd like
Remove over 1500+ dependencies from the published package.
Use marked and pure JS ffs. That a total of 1 package.

Describe alternatives you've considered
Doing that myself.

Are you able to assist to bring the feature to reality?

cd storybook
rm -rf ./
npm init
npm i marked --save-dev
touch index.js
