Unable to install eks anywhere with kindnetd cni due to image tags in public.ecr.aws have been changed.

**What happened**:
kindnetd image tag has been changed on public.ecr.aws from v0.18.0 to v0.18.0-eks-a-45

**What you expected to happen**:
This cause issue to install eks anywhere on docker when cillium cni has issue to start.

**How to reproduce it (as minimally and precisely as possible)**:
on clean docker factory setting.
run

`CLUSTER_NAME=mgmt
eksctl anywhere generate clusterconfig $CLUSTER_NAME \
--provider docker > $CLUSTER_NAME.yaml`

Then update mgmt.yaml from cilium to kindnetd
Then run
`eksctl anywhere create cluster -f $CLUSTER_NAME.yaml`

then use docker ps to inspect hang installation and you will see the image was unable to be pulled down for cni.

**Anything else we need to know?**:

**Environment**:
- EKS Anywhere Release: 0.18.3
- EKS Distro Release: 1.28

Reproduce the failure with the provided eksctl anywhere generate clusterconfig and create cluster commands, then inspect mgmt.yaml and the Docker containers with docker ps. Trace the kindnetd image reference used for the Docker provider and update it to the available public.ecr.aws tag. Done means a clean Docker installation can pull the kindnetd image and complete cluster creation.
