Test and add AWS ECR to the list of supported registries

[radu-matei]

According to this blog post, AWS ECR should have support for storing OCI artifacts, meaning it should accept Wasm modules as well. We should test that this is the case, then add it to the list.

If anyone with an AWS account wants to test it, that would be great!

I can test this

I came here to post an issue to track a potential PR and I found this one. Cool.

I have tested it a few minutes ago and it (seems) to work just fine:

$ aws ecr get-login-password --region us-west-2 | docker login --username AWS --password-stdin 693935722839.dkr.ecr.us-west-2.amazonaws.com
Login Succeeded

PS the subject of this issue says ECS but it should really say ECR PS2 also note that the 693935722839.dkr.ecr.us-west-2.amazonaws.com/python3.wasm repository needs to exist because ECR does not (yet) support create on push.
