Angular Material Stepper

Is your feature request related to a problem? Please describe.

The angular material renderer does not support the stepper provided by angular material.

Describe the solution you'd like

Would be good if it renders a material stepper when I define the option variant: "stepper" in an angular material project since that is an option in the docs. And maybe add the orientation to it as described in #1817 (which would be simply another option instead of a new renderer)

Describe alternatives you've considered

I considered just using jsonforms inside a stepper instead.

Inizia individuando il renderer di Angular Material e il modo in cui vengono rappresentate le varianti del renderer. Esamina l’opzione stepper descritta nell’issue e la discussione sull’orientamento in #1817, quindi verifica che variant: "stepper" esegua il rendering di uno stepper di Angular Material con il comportamento di orientamento richiesto.
