Follow up to 98264a13

Resolved by https://github.com/ruby-concurrency/concurrent-ruby/pull/529

Fixes #24627.

Unlike `one?` and `none?`, `empty?` has interactions with methods
outside of enumerable. It also doesn't fit in the same vein.
`Topic.any?` makes sense. `Topic.empty?` does not, as `Topic` is not a
container.

Fixes #24808
Close #24812
