"Next steps with Tracing" is out of date

[WesleyAC]

Next steps with Tracing recommends the following:

# Implements the types defined in the Otel spec
opentelemetry = "0.17.0"
# Integration between the tracing crate and the opentelemetry crate
tracing-opentelemetry = "0.17.2" 
# Allows you to export data to Jaeger
opentelemetry-jaeger = "0.16.0"

However, opentelemetry-jaeger is deprecated and these are very old versions. This should be updated with the current best practices.
