Changes

As discussed in #1131, it looks like Laravel won't be making this change in the near future. This PR prevents errors such as this:

Parameter #1 $callback of method Illuminate\Database\Eloquent\Factories\Factory<Illuminate\Database\Eloquent\Model>::afterCreating() expects 
    Closure(Illuminate\Database\Eloquent\Model): mixed,
    Closure(App\Data\Models\Task): void given.
