tracing: update Jaeger instructions, remove 'HTTP tracing' text (#1572)

Jaeger exporter has been deprecated a long time, and we removed it a
long time ago - seems I missed some docs back then

Part of
https://linear.app/sourcegraph/issue/SVC-2059/otel-remove-jaeger-export-option-by-70

Also, it's tracing, not HTTP tracing, and we use tracing extensively for
background work
