Requires @angular/cdk/portal by default

[rustam-mukhametshin]

Describe the bug Cant use charts and start serving ng app with defaults.

To Reproduce

1. Init new project with ng new newProject (11/12 angular).
2. Do npm i @swimlane/ngx-charts --save
3. Add BarChartModule to AppModule
4. Add <ngx-charts-bar-vertical></ngx-charts-bar-vertical> to app.component.html
5. Run ng serve
6. See error that requires @angular/cdk/portal

Expected behavior Serving ng app and seeing empty html, if passed no data in results property. Without requiring @angular/cdk/portal

Screenshots

Demo

• Stackblitz: While installing Swimlane, Stackblitz alerts that it requires @angular/cdk/portal, it's not obvious for running on localhost.

Same issue except for 17.0.1 doesn't work for me either.
