You should rename 'category' field to 'categories' :

...
'categories'=>[
     'type' => Type::listOf(GraphQL::type('Category'))
],

Or write this code in the resolver function:

protected function resolveCategoriesField($root,$args)
{
   // you may have some code here...

    return $root->categories; // this relationship must be defined in the product model
}
