Setup not working as of #164

[eapache-opslevel]

👋 @rmosolgo I'm trying to upgrade 0.5.3 -> 0.5.4 of this gem locally, which pulls in your change in #164.

I'm now getting the following error whenever a query tries to batch load:

Cannot create loader without an Executor. Wrap the call to for with GraphQL::Batch.batch or use GraphQL::Batch::SetupMultiplex as a query instrumenter if using with graphql-ruby

Looking at the full backtrace, I no longer see graphql-batch code in there anywhere, so presumably the new GraphQL::Batch::SetupMultiplex::Trace is not getting triggered for some reason.

Our schema class still has use GraphQL::Batch at the bottom, so I'm not sure what's going on. I'll keep looking to see why it's not getting wrapped properly.

(this is with graphql-ruby 2.1.11, ruby 3.2.2, rails 7.1.3)

OK, this has to do with our use of trace modes... not sure if the bug is in our code or in graphql-ruby, but it's not in graphql-batch.
