Add the `scheduler-host-address=""` as a production recommendation

[alicejgibbons]

What content needs to be created or modified? Setting the dapr.io/scheduler-host-address annotation is not recommended for most apps as the scheduler should connect to all daprd processes by default allowing the apps to use actors, workflows and jobs. However, seeing the only place this annotation is documented today is here, this needs to be in a more prominent place in the docs, likely here for services that dont use the aforementioned APIs.

Where should the new material be placed? https://docs.dapr.io/reference/arguments-annotations-overview/ https://docs.dapr.io/concepts/dapr-services/scheduler/
