chore(readme): change .angular-cli.json reference to angular.json for…

… Angular6 (#374)

* Angular6 .angular-cli.json --> angular.json

README used old angular-cli.json vs new angular.json. This PR fixes that.

* angular.json is a top level directory, same as node_modules. Updating filepath to reflect.
