Multi-platform build failing due to outdated skopeo in ubuntu-latest

A basic multi-platform build workflow currently fails:

workflow.yml

```yml
on: [push]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- uses: docker/setup-qemu-action@v2
with:
platforms: arm64
- uses: docker/setup-buildx-action@v2
- uses: docker/login-action@v2
with:
registry: ghcr.io
username: ${{ github.actor }}
password: ${{ github.token }}
- uses: devcontainers/ci@v0.2
with:
imageName: ghcr.io/${{ github.repository }}/devcontainer
platform: linux/amd64,linux/arm64
```

The error:

```
Error: Dev container build failed: Command failed: docker tag vsc-repository-d8fa4a8f8a3fefdc0feb211b3b07a31c-features ghcr.io/organization/repository/devcontainer:latest (exit code: undefined)
An error occurred building the container.
Error: Command failed: docker tag vsc-repository-d8fa4a8f8a3fefdc0feb211b3b07a31c-features ghcr.io/organization/repository/devcontainer:latest
```

Single-platform builds are working fine.

I don't think this is relevant, but just in case:

.devcontainer/devcontainer.json

```json
{
"image": "mcr.microsoft.com/devcontainers/base:jammy",
"features": {
"ghcr.io/devcontainers/features/node:1": {}
},
"updateContentCommand": ".devcontainer/install.sh"
}
```
