docs: Exports the module with the variables from the session in `path`.
  
      Note that it is the module definition in the ModuleSpec used to create this
      module that gets exported. The session is only used to provide the value
      of variables.
  
      Args:
        path: path where to export the module to.
        session: session where to export the variables from.
  
      Raises:
        RuntimeError: if there is an issue during the export.
