api: change <pk> parameter to <cover_id> for cover comments endpoint

Rename cover lookup parameter `pk` to `cover_id` for the cover comments
list endpoints to disambiguate from the lookup parameter `comment_id` in
upcoming patches which introduces the cover comments detail endpoint.
This doesn't affect the user-facing API.
