[BUG] error while using action

[Vodianoi]

Error: 'ghcr.io/greentf/utp:latest' should be either '[path]/Dockerfile' or 'docker://image[:tag]'.

Is it supposed to be used in Docker environment ?

Evidently I do need the docker:// scheme in the image URL. For whatever reason it worked fine in my testing in this repo but breaks in other repos? Should have it fixed later tonight.

should be fixed by #13
