Subject: [PATCH] fix: use unique otelconfPath on Windows to avoid duplicate
 volumeMount

The datadog.otelconfPath template resolves to C:/ProgramData/Datadog on
Windows, identical to datadog.confPath. This causes the otel-agent container
to have two volumeMounts at the same mountPath, which Kubernetes rejects:
mountPath must be unique.

Uses C:/ProgramData/Datadog/otel-agent instead, matching the Linux pattern
where confPath (/etc/datadog-agent) and otelconfPath (/etc/otel-agent) are
distinct directories.
