Replace ApolloTracing with simple tracing extension

[rafalp]

Instead of ApolloTracing (which is deprecated) we could implement a simple extension that adds extensions: {traces: []} object where each trace would be a separate {path: time: }.

I don't know how useful this would be to folk, but maybe it would have some utility as simple example extension?

As an example in the docs or a examples/ directory, sure, but releasing it as an official feature I think would only make sense if/when GraphiQL2 adds support for a standardized format to visualize it

[dacevedo12]

I think it's easier to advise using OTel with Jaeger to visualize traces locally

[rafalp]

World doesn't end on GraphiQL, OT and Jaeger tho. There are plenty GraphQL APIs here that are very limited in scope, run on things like AWS lambda and are interacted with through Insomnia or Postman. Having minimal zero-setup tracing extension to see how fast or slow resolvers are may be of use there.

Alternative is just marking ApolloTracing as deprecating and deleting it in one of future releases.
