Running ember-cp-validations using typescript

### Environment

- Ember Version: 3.20.2
- Ember CLI Version: 3.20.2
- Ember CP Validations Version: 4.0.0-beta.10
- Typescript: 4.5.4

### Steps to Reproduce

Hello everyone! I'm using native class in my project and we're migrating to Typescript. We have models like this in the current project:
```js
const Validations = buildValidations({
name: [
validator('presence', true),
]
});

export default class UserModel extends Model.extend(Validations) {
...
}
```

when changing to typescript the Model.extend(Validations) stops working. Does anyone have an alternative? I've seen decorators like hasValidations implemented in the past, but it's been removed. I wanted to know if we have any alternative for the typescript. Thanks!
