[Bug]: Support for ResrouceCollection

[abdul-alhasany]

What happened?

Does the library support ResourceCollection?

How to reproduce the bug

I have a ResourceCollection similar to this:

<?php

namespace App\Http\Resources;

use Illuminate\Http\Request;
use Illuminate\Http\Resources\Json\ResourceCollection;

/**
 * @mixin \App\Models\ModelName
 */
class ResponseResourceCollection extends ResourceCollection
{
    /**
     * Transform the resource into an array.
     *
     * @return array<string, mixed>
     */
    public function toArray(Request $request): array
    {
        return $this->collection->transform(fn($item) => $this->transformItem($item))->toArray();
    }

    protected function transformItem($item): array
    {
        return [
            'id' => $item->id,
        ];
    }
}

When running the php artisan runtype:generate command I get this error:
Attempt to read property "id" on array

I also tried changing the mixin to:

/**
 * @mixin \Illuminate\Database\Eloquent\Collection<\App\Models\ModelName>
 */

but I got this error Undefined property: ReflectionClass::$id

Just run into this as well.

@watzon @abdul-alhasany this is due to the fact that the transform method on the collection modifies the underlying collection. transform

When processing the modifiers, these references have been transformed into an array. Then the next time they get processed, they're no longer objects and thus throwing this error.

I will look into it, however if you change transform into map it should work.
