Fix codespaces container creation (Azure#13338)

The base image now contains the same logic for installing Docker, 
so by the time our custom file ran Docker was already installed which 
causes Codespaces creation to error.

This commit does a few things:

1. It restores our ability to use codespaces for development
2. It installs rush globally
3. It disables Oryx's default behavior for node since it conflicts with `rush`
