[BUG] K8s 1.34.x doesn't allow short-name image names

Describe the bug
On K8s 1.34.x the Nginx image can't be pulled due to this error:
Failed to inspect image "": rpc error: code = Unknown desc = short name mode is enforcing, but image name nginx/nginx-ingress:5.2.1 returns ambiguous list

Fix
The fix is to define the repository as well:

...
  image:
    ## The image repository of the Ingress Controller.
    repository: docker.io/nginx/nginx-ingress
