[BUG] Unhandled exception. System.IO.FileNotFoundException: The configuration file 'configuration.prod.yaml' was not found and is not optional.

### Release version

v6.0.1

### Describe the bug

Following the current instuctions for v6.0.1 I didn't see references to create this file. configuration.prod.yaml. I have a github environment with the secrets from the documentation but the GH action fails until you create the file.

### Expected behavior

action should continue if you do not have any GH environment overrides and the file does not exist or the documentation may need to be updated.

### Actual behavior

created a blank file and the error goes away.

### Reproduction Steps

run through the APIOPs documentation in a new GH repo. publish your first change to an API and promote up to prod.
