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
