$prodduct->description[] = [
'description1' => $description1;
'description2' => $description2;
];
$product->save();

Answer 1

If you cast the description field to be an array in your model, you can update your controller code to:
$prodduct->description = [
'description1' => $description1;
'description2' => $description2;
];
To cast the field to an array, add this to your ProductAdd Model:
$casts = [
'description' => 'array'
];
