"No authentication found" warning is thrown when using Application Default Credentials

[Igor Sarkisov]

TL;DR

We use Application Default Credentials on our self-hosted runners. As such, we don't need to use google-github-actions/auth action. With such set up, google-github-actions/setup-gcloud throws the following warning:

Warning: No authentication found for gcloud, authenticate with google-github-actions/auth

Expected behavior

Warning shouldn't be thrown as we are already authenticated.

Observed behavior

Warning is thrown.
