fix(deps): [Release 3.6.x] Update dskit to resolve Otel conflict

[bboreham]

What this PR does / why we need it:
This is the same dependency change from #19562, backported to the release-3.6.x branch.
The symptom was:

err="failed to initialise trace resource: conflicting Schema URL: https://opentelemetry.io/schemas/1.37.0 and https://opentelemetry.io/schemas/1.34.0"

This dskit update removes 1.34.0 so the conflict goes away.
It also makes a small change in tracing, with no outward effect.

Which issue(s) this PR fixes:
Fixes #19975
