Incorrect instructions on how to run the Workflow quickstarts

[grafvonb]

Describe the issue
All language versions of the workflow quickstarts incorrectly state that to run the order processor app, one must navigate to the sdk/order-processor folder (Step 2) and execute dapr run -f . (Step 3). This results in an error: Failed to get run file path: error in validating the file path "dapr.yaml": error in getting the file info for dapr.yaml: stat dapr.yaml: no such file or directory. The error occurs because the dapr.yaml file is actually located in the workflows/<lang>/sdk folder, not within the workflows/<lang>/sdk/order-processor folder.

URL of the docs
https://docs.dapr.io/getting-started/quickstarts/workflow-quickstart/

Expected content
The documentation should be updated to instruct users to navigate to the workflows/<lang>/sdk folder in Step 2.
