image docker id (digest of image config) is not supported in nerdctl inspect

### Description

Image docker id (digest of image config) is not supported in nerdctl inspect

Is this intentional? Should we try to support it or add documentation to warn users that it is not supported?

### Steps to reproduce the issue

1. `nerdctl pull public.ecr.aws/amazonlinux/amazonlinux:2`
2. `nerdctl image inspect public.ecr.aws/amazonlinux/amazonlinux:2`
3. `nerdctl image inspect `

### Describe the results you received and expected

```
FATA[0000] 1 errors:
no such image:
```

In docker, it can work.

### What version of nerdctl are you using?

1.4.0

### Are you using a variant of nerdctl? (e.g., Rancher Desktop)

None
