feature request: do not leak image names that use secrets in github comments

[pozsa]

If the image uses a secret the value of the secret is leaked in the github comment.

In the example image below the image reference leaks the value of secrets (if they are used for the image name). In case a secret is used as part of the image name the image reference should display *** for the secrets instead of leaking them.

some examples: ***/scout-demo-service:main, docker/scout-demo-service:***, ***/***:latest
