Mark RuboCop::AST::EnsureNode as being in a void context.

[Earlopain]

ensure nodes are somewhat special in that their last expression will not get implicitly returned.

def foo(do_rescue:)
  puts "begin called"
  raise if do_rescue
  "begin"
rescue
  puts "rescue called"
  "rescue"
ensure
  puts "ensure called"
  "ensure"
end

puts foo(do_rescue: false)
puts "----"
puts foo(do_rescue: true)

# =>
# begin called
# ensure called
# begin
# ----
# begin called
# rescue called
# ensure called
# rescue

This change will make it possible to properly teach Lint/Void about it.
