Describe the Bug
When creating a modal using ModalController, the property willAnimate does not appear to be part of the interface causing editors to flag an error:

Object literal may only specify known properties, and 'willAnimate' does not exist in type 'ModalOptions'.

Project then won't compile.

Steps to Reproduce

Create a modal using ModalController and specify the willAnimate property in the options using a TypeScript aware editor.

Related Code

    const modal = await this.modalCtrl.create({
      component: ModalComponent,
      willAnimate: false,
    });

[JamieWritesCode]

The ModalOptions interface is declared at @ionic\core\dist\types\components\modal\modal-interface.d.ts and clearly doesn't have the willAnimate property in it.

Adding the line willAnimate?: boolean; to the interface allows me to compile and the functionality appears to work as expected. Is this property being phased out or phased in?

export interface ModalOptions {
    component: ComponentRef;
    componentProps?: ComponentProps;
    showBackdrop?: boolean;
    enableBackdropDismiss?: boolean;
    enterAnimation?: AnimationBuilder;
    leaveAnimation?: AnimationBuilder;
    cssClass?: string | string[];
    delegate?: FrameworkDelegate;
    willAnimate?: boolean;
}
