Subject: refactor(components): rewrite Code component and usePrism hook

* move Prism styles to Sass placeholders to avoid repeats
* let usePrism consumer define its plugins (remove default ones)
* remove `plugins` prop from Code component
* add new props to Code component to let consumer configure plugins
(and handle plugin list from the given options)

However there are some problems with Prism plugins: line-highlight and
treeview does not seems to be loaded. I don't want to use Babel instead
of SWC so I have no solution for now.
