Migrate from jaeger-client-go to opentelemetry-go

[Juan Calderon-Perez]

@Shareed2k I really appreciate this middleware, it makes tracing super easy to do in Fiber.

Recently while looking at the code I notice that it uses: https://github.com/jaegertracing/jaeger-client-go

Which is now deprecated in favor of: https://github.com/open-telemetry/opentelemetry-go
