Request: built-in support for opentelemetry

[magicmark]

Would you be open to a PR with an option to enable out-the-box opentelemetry tracing?

Thanks!

I would rather not add another dependency/complication to the code. What is the use case here? Could that not be added using another way, by monkey-patching some methods?

Fair enough.

(prior art fwiw: https://github.com/mirumee/ariadne-codegen?tab=readme-ov-file#open-telemetry)

I expect the otel boilerplate might be fairly minimal. Maybe something for folks to copy/paste in docs/code_examples would suffice.
