class RuboCop::Cop::Chef::Correctness::NotifiesActionNotSymbol

When notifying or subscribing actions within a resource the action should always be a symbol. In Chef Infra Client releases before 14.0, this may result in double notification.

@example

### incorrect
execute 'some command' do
  notifies 'restart', 'service[httpd]', 'delayed'
end

execute 'some command' do
  subscribes 'restart', 'service[httpd]', 'delayed'
end

### correct
execute 'some command' do
  notifies :restart, 'service[httpd]', 'delayed'
end

execute 'some command' do
  subscribes :restart, 'service[httpd]', 'delayed'
end
