`AlwaysSample()` will include spans whose parents were not sampled, which is generally unwanted as it leads to leaf nodes without parents in the telemetry graph. This change updates the jaeger setup to use the [otel spec default] `ParentBased(AlwaysSample())` which fixes this issue.

Further comments
This parent-based behavior was used in this repo via the jaeger-client-go library before the switch to otel as that exporter always defers to parent span sampling decisions.
