Missing Property for DialogConfig in buefy/types/components.d.ts

[service-paradis]

Overview of the problem

Buefy version: 0.7.5
Vuejs version: 2.6.10

Description

The property focusOn is missing for DialogConfig in buefy/types/components.d.ts. I have lint errors when I'm trying to use this property.

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

Steps to reproduce

1. Use Vue and Typescript
2. Use $dialog plugin to create a dialog
3. Set the property focusOn to focus on cancel
4. Run tslint
   ex.

this.$dialog.confirm({
        title: 'Confirmation',
        message: `This will delete the universe. Do you really want to do this?`,
        cancelText: 'Nope, sorry',
        confirmText: 'Sure!',
        type: 'is-danger',
        hasIcon: true,
        focusOn: 'cancel',
        onConfirm: () => this.deleteUniverse(),
    });

Expected behavior

Linter should be OK with this.

Actual behavior

Linter is displaying an error:

Argument of type '{ title: string; message: string; cancelText: string; confirmText: string; type: string; hasIcon: true; focusOn: string; onConfirm: () => void; }' is not assignable to parameter of type 'DialogConfig'.
  Object literal may only specify known properties, and 'focusOn' does not exist in type 'DialogConfig'.
