devcontainer build with --push true failed when use image property

**devcontainer version**: `0.27.1`

#### devcontainer.json with image property

```json
{
"name": "kaitian-devcontainer",
"image": "mcr.microsoft.com/devcontainers/javascript-node:14",
"features": {
"ghcr.io/stickmy/merchant-legacy-dev-features/kaitian:1.0.1": {}
}
}
```

#### command

```bash
devcontainer build --workspace-folder . --image-name ghcr.io/stickmy/kaitian-devcontainer:1.0.0 --push true
```
The error message:
```
=> ERROR pushing vsc-kaitian-devcontainer-27da8ffe3eebb26605196a518a9f1f

```

But the build works with `build` property

```json
{
"name": "kaitian-devcontainer",
"build": {
"dockerfile": "Dockerfile",
"args": {
"VARIANT": "14"
}
},
"features": {
"ghcr.io/stickmy/merchant-legacy-dev-features/kaitian:1.0.1": {}
}
}
```

**Dockerfile**

```
ARG VARIANT="14"
FROM mcr.microsoft.com/devcontainers/javascript-node:${VARIANT}
```
