Add support for stencil template

I want to start a PWA + mobile app using Stencil and Ionic. It would be convenient to be able to do that using the cli.

After some research, I only found this way:
- npm init stencil: generate a PWA with stencil and ionic installed and configured
- Install capacitor and add android and ios targets as documented here https://capacitorjs.com/solution/stencil.

Is there something I'm missing to get equivalent results like the cli?

If it's not in the scope of the CLI, can you indicate how I can do that manually?
