The app needs to be updated quite a bit. Angular deprecated support for protractor a few versions back. Might want to check out https://goo.gle/state-of-e2e-in-angular for details. Similarly, tslint has been replaced by eslint. And core-js-pure just puts up a messaging telling you not to even use it any more.

That's if you can get past step one, since npm install fails. I had to to npm install --force just to get it to work.
