Description

🚀 Feature

Are there any examples of something like this using OpenTelemetry's go SDK? Would a tracing wrapper still be required?

Research direction
The issue asks for an OpenTelemetry Go tracing example that propagates spans through the grpc gateway. Currently, the project has documentation for OpenTracing [here](https://grpc ecosystem.github.io/grpc gateway/docs/operations/tracing/#opentracing support). The task is to create a similar example using OpenTelemetry's Go SDK, possibly adapting the existing tracing wrapper. Check the existing tracing source code in the repository and any related comments or issues for guidance. The example should demonstrate how spans propagate from gRPC to HTTP endpoints.
