Cannot find module '@babel/polyfill'

I installed the latest version of the templates: `dotnet new -i aurelia.dotnet.templates`

I then created a new folder and within the folder did the following `dotnet new aurelia`

Once that was completed, I then did an `npm install` to ensure all my packages were loaded. I then ran the project (which should be a very basic Hello World) and I get an error stating that

>Cannot find module '@babel/polyfill'

The error occurs during the webpack build of `main.ts`.

What do I need to do to get this working? I kind of figured the initial template would just work out of the box.

I also tried: `au build` and got the following


I tried `npm install babel-polyfill` but that didn't fix anything.

Reproduce the generated Aurelia project from the dotnet template, run npm install, and inspect the webpack build of main.ts where @babel/polyfill cannot be found. Check the generated package dependencies and build configuration; done means a fresh template project builds successfully without the missing-module error.
