fix: propagate trace context to Snapshot in new-model snapshot creation

Konflux-CI ADR 0061 requires the build PipelineRun's trace context be persisted
onto the Snapshot so the delivery trace continues forward through
integration and release. The old-model adapter does this explicitly.
The new-model PrepareSnapshotForPipelineRun (ComponentGroup-based)
never did, leaving Snapshots created via the new path without a
pipelinerunSpanContext annotation and breaking the trace chain for
every delivery that exercises ComponentGroup workflow.

Mirror the existing old-model behavior with a verbatim copy of
tekton.dev/pipelinerunSpanContext from the build PipelineRun to the
Snapshot, and assert the propagation with a targeted unit test on
PrepareSnapshotForPipelineRun.
