Unable to push an image to ECR

Hi Packer Docker plugin team, I observed this peculiar issue.

#### Overview of the Issue

Post-processor docker-push fails when it tries to push an image to the ECR. Both build and login were successful. If I try to push the docker image manually (doing docker push myself) it succeeds.

#### Reproduction Steps

Run packer build

### Plugin and Packer version

From `packer version 1.8.3` and `plugin version 1.0.8`

### Simplified Packer Buildfile

```
packer {
required_plugins {
docker = {
version = "1.0.8"
source = "github.com/hashicorp/docker"
}
}
}

source "docker" "jdk" {
image = "public.ecr.aws/docker/library/openjdk:20-slim-bullseye"
commit = true
platform = "linux/amd64"

changes = [...]
}

build {
name = "jdk_image"
sources = [
"source.docker.jdk"
]

provisioner "shell" {
inline = [...]
}

post-processors {
post-processor "docker-tag" {
repository = "${var.aws_account_id}.dkr.ecr.${var.aws_region}.amazonaws.com/${var.image_name}"
tags = [var.image_tag]
}

post-processor "docker-push" {
ecr_login = true
login_server = "https://${var.aws_account_id}.dkr.ecr.${var.aws_region}.amazonaws.com"
}
}
}
```
### Operating system and Environment details

macOS Monterey 12.6, Darwin 21.6.0 Darwin Kernel Version 21.6.0, Docker with Colima VM
