This can be fixed by configuring pagination to fetch the resource by keyset
(so keyset is only ever primary key), but will perform worse because
we have to fetch the record. If someone would like to implement this,
let me know.
i.e. warnings that appear when you run `mix docs`
Although this PR doesn't fix the majority of them, since the majority
are errors from referring to `@moduledoc false` modules in docs and typespecs.
