docs: Add initial version of Docusaurus based docs

This change updates the repository with a new Docusaurus-based
documentation website. This allows us to create our documentation using
Markdown, MDX and React. This will serve as the main entry point for
users visiting https://opendc.org. The actual OpenDC application will be
moved to https://app.opendc.org.
