switch to new builder for Docker

I did not have cargo installed on my system when I first tried to build the repo from a fresh git clone (I had not noticed it was a rust project), and it wasn't called out as a dependency for installation from source. I've added it as a noted dependency with some quick, collapsible installation instructions I followed to get it installed.
