In `@pipeline/inputs/event-tracing-windows.md`:
- Line 35: Clarify the provider identity validation in the event tracing Windows
docs: the check should compare the resolved provider GUID against the configured
provider_guid, not the provider name. Update the wording around the provider
session rules so it explicitly says provider_guid, provider_name, or both may be
set, and if both are set the resolved GUID must match the configured GUID; use
the provider/session terminology consistently in this section.
