ember/no-assignment-of-untracked-properties-used-in-tracking-contexts applied on `@attr`

The rule `ember/no-assignment-of-untracked-properties-used-in-tracking-contexts` is reporting error for codes like:

```typescript
export default class EnvironmentPermissions extends Fragment {
@service declare store: StoreService;

@attr('number') declare environmentId: number;

get environment(): Environment | null {
return this.store.peekRecord('environment', this.environmentId);
}

set environment(value: Environment | null) {
// Here I get the error
this.environmentId = value && Number.parseInt(value.id, 10);
}
```

But in the doc they don't talk about using `set` on model so I'm pretty sure it's a mistake
