* Allow callable to modify withPersonalTeam

I want this in jetstream projects, and it feels like something others would also want. It helps to set up the seeder in a Laravel Jetstream Project quickly.

For example:

```php
User::factory()->withPersonalTeam(
            fn (TeamFactory $factory) => $factory
                 ->state([
                     'foo' => 'bar',
                  ])
                 ->has(
                     Post::factory()
                          ->count(10)
                 )
)
        ->create();
```

* Update UserFactory.php

* formatting

In my installation, these tests fail because the user doesn't have the `two_factor_confirmed_at` attribute:
```
The attribute [two_factor_confirmed_at] either does not exist or was not retrieved for model [App\Models\User]. (View: /var/www/html/vendor/livewire/livewire/src/views/mount-component.blade.php)
```

I believe this is because the factory doesn't specify the attribute.

I considered updating the factory to include it (set to `null`), but then I thought it might be a little messy because there should be a check to see if the feature's enabled.

This solution, however, requires everyone to remember to get a fresh user instance, when needed, without it being clear as to why.

So...let me know if I should try a different approach...
