fix: add logic in runner to check to make sure that PULUMI is configured with a token

[qdzlug]

Describe the bug If you have not initialized Pulumi or set the PULUMI_AUTH_TOKEN environment variables you will get some pretty ugly error messages when you run:

environment file [/home/ubuntu/kic-reference-architectures/config/pulumi/environment] passed validation
Stack configuration file [/home/ubuntu/kic-reference-architectures/config/pulumi/Pulumi.marajenks55.yaml] passed validation
All configuration is OK

 code: 255
 stdout: 
 stderr: error: PULUMI_ACCESS_TOKEN must be set for login during non-interactive CLI sessions

To Reproduce Steps to reproduce the behavior:

1. Run w/o pulumi configured.
2. Boom!

Expected behavior Should check and prompt user to either login to pulumi or set the environment variable.

Your environment n/a
