Update jaeger versions
Created by: ferozsalam
This takes us to Golang 1.18 on jaeger, which contains several security fixes in jaeger's dependencies.
There's only a single breaking change that's relevant – in v1.29.0, a deprecated CLI flag that we don't appear to use was removed. See https://github.com/jaegertracing/jaeger/releases/tag/v1.29.0
