Describe the bug
I am trying to run taskcat in Docker as per https://aws-ia.github.io/taskcat/installation/#docker

This fails with an "image not found" error:

docker pull public.ecr.aws/aws-ia/taskcat:latest
Error response from daemon: manifest for public.ecr.aws/aws-ia/taskcat:latest not found: manifest unknown: Requested image not found

I tried this on both my home PC and on an EC2 instance, same error from both machines.

Steps to reproduce the behavior:

1. docker pull public.ecr.aws/aws-ia/taskcat:latest

Expected behavior
Image gets pulled
