Switch the image from docker.io to gcr mirror

Docker hub reduced its rate limit to a 100 container pulls per hour. This is very small and making our tests flaky. As a stop gap, we think that changing to `mirror.gcr.io` will get us past the rate limit since the image will be pushed from the artifact registry cache instead of docker hub.
