Mutator can not handle array

[hans-thomas]

Hi,
As mentioned in #2634, creating a mutator for the array type attribute will throw an error while setting the value to the attribute. This error will be thrown because of the invalid value prepared for the update action. So I override normalizeCastClassResponse method from Illuminate\Database\Eloquent\Concerns\HasAttributes trait and force it to add the key name all the time.

So if we have something like this on our model class

protected function skills(): Attribute
{
    return Attribute::make(
        get: fn ($value) => $value,
        set: fn ($values) => array_unique($values)
    );
}

we do not get an error anymore.

@GromNaN I think this would be fix this issue. Now it's supporting mutators that return [ key => value ] to change the key name and also mutators that return an array of values. I write tests for both to prevent any breaking changes in the future.

So if the field's key can be an integer, this can't fix the problem and I think there is no way to solve this. Thank you for your time❤️
