SiteId placeholder is not working in TelemetryTopicTemplate using Dapr transport

[Haeavar]

Describe the bug
If I set the --SiteId commandline parameter to "xyz" and use it in the --TelemetryTopicTemplate commandline parameter like "events.{SiteId}.{PublisherId}" it does not get replaced. Its still SiteId. PublisherId works as expected.

To Reproduce
Steps to reproduce the behavior:

1. Set commandline parameters to
   --SiteId=xyz
   --PublisherId=0815
   --TelemetryTopicTemplate=events.{SiteId}.{PublisherId}
   --DefaultTransport=Dapr
2. Run OpcPublisher

Expected behavior
The message topic should be "events.xyz.0815" but is "events.SiteId.0815"

Additional context
Using mcr.microsoft.com/iotedge/opc-publisher:2.9.4-preview3
