[11.x] Adds support for Attribute return mutators to the Eloquent/Builder pluck method

[MattBradleyDev]

Adds support to the src/Illuminate/Database/Eloquent/Builder::pluck method for attribute return type mutators to correctly apply just as they do when using the get{$column}Attribute methods.

/**
 * Interact with the user's first name.
 */
protected function firstName(): Attribute
{
    return Attribute::make(
        get: fn (string $value) => ucfirst($value),
    );
}

$plucked = User::query()->pluck('name', 'id');
