Shift `dependencies` to `devDependencies`.

The `reveal.js` npm module is typically installed to access the CSS/JS
assets for Reveal.js. For those that want to run the plugins, they would
clone the whole repository. Hence, it doesn’t make sense to include
those as `dependencies`, which will increase download times.

Closes #1734.
