[Workflow] Fix default GRPC port to 50001

[olitomlinson]

As it stands, the default GRPC port for Workflows is not set to 50001.

Which means the OOTB experience is not as slick as it could be, as the DAPR_GRPC_PORT env var needs to be set to 50001 manually.

If the default was 50001, then this would make the OOTB experience slicker.

This has already caused some confusion for early adopters, as discussed on Discord.

@olitomlinson - The default is 50001 in what case are you not seeing that be true?

Chris G has confirmed this is a problem with Workflows SDK. It's also reported by other users over on Discord.

I get this :

I think the underlying Durable Task SDK is defaulting to 4001, which is not what the Dapr SDK defaults to (as you have quite rightly pointed out, its 50001.

So to mitigate this, If I add an env var to my App :

DAPR_GRPC_PORT : 50001

it now works :

I suspect it's this which is not being overriden :

address = "http://localhost:4001";

I've validated that this is now fixed in the latest pre-release 1.12.0-rc02

Thanks folks!
