FIX: Can't dismiss new topics that belong to a sub-sub category (#22849)
What is the context for this change?

Prior to this change, there is a bug in `TopicsController#reset_new`
where it does not dismiss new topics in sub-subcategories when the
`category_id` and `include_subcategories=true` params are present. This
is because the controller did not account for sub-subcategories when
fetching the category ids of the new topics that should be dismissed.

This commit fixes the problem by relying on the `Category.subcategory_ids` class
method which accounts for sub-subcategories.
