New Arr::select() and Collection::select() convert item objects to arrays

[Icexist]

10.44.0 added the Collection::select() and Arr::select() methods #49845 and 10.45.0 updated it to work with ArrayAccess #50072

However, these convert any item in either an array or the Collection into an array even if it is an object. See https://github.com/laravel/framework/blob/11.x/src/Illuminate/Collections/Arr.php#L532-L533

For example, if you have an array of objects and select a single column, it will become an array of arrays.

$obj1 = new \stdClass;
$obj1->color = 'blue';
$obj1->temperature = 'warm';

$obj2 = new \stdClass;
$obj2->color = 'green';
$obj2->temperature = 'cool';

$arr = [$obj1, $obj2];

$selected = Arr::select($arr, 'color');
/* 
[
    [ 'color' => 'blue' ],
    [ 'color' => 'green' ],
]
*/

This has caused unexpected behavior and I'm wondering a few things:

1. Did I make a bad assumption that Collections can only have items of one type (array or object)?
2. Is this behavior (converting all object items into arrays) intended?
3. Should I submit a PR to update the Arr::select() (and the LazyCollection) to return elements as objects?

For example, in illuminate/collections/Arr.php

    /**
     * Select an array of values from an array.
     *
     * @param  array  $array
     * @param  array|string  $keys
     * @return array
     */
    public static function select($array, $keys)
    {
        $keys = static::wrap($keys);

        return static::map($array, function ($item) use ($keys) {
            $result = [];

            foreach ($keys as $key) {
                if (Arr::accessible($item) && Arr::exists($item, $key)) {
                    $result[$key] = $item[$key];
                } elseif (is_object($item) && isset($item->{$key})) {
                    $result[$key] = $item->{$key};
                }
            }

-           return $result;
+           return is_object($item) ? (object) $result : $result;
        });
    }

I've put together an implementation of this solution but would like some eyes on it before I submit a PR directly, just for review's sake. Hopefully someone would be able to take a look!
