kaniko: Regression: Kaniko 1.7 unstable authentication against GCP Artifact Registry

Actual behavior While building several containers against GCP Artifact Registry via skaffold we are getting intermittent authentication failures.

Prior to invoking skaffold we issue:

docker-credential-gcr configure-docker --registries=us-east4-docker.pkg.dev

Expected behavior We expect pushes continue to work throughout the whole build.
