It seems the terraform state for resource `envbuilder_cached_image` is never updated with the pushed image value:

```

As the log states, push was successful (double-checked that the image SHA is available on GHCR side). However, while restarting the workspace, during the `Planning infrastructure` phase on Coder:
```
The previous state specifies image == builder_image "ghcr.io/coder/envbuilder:1.1.0", which indicates a previous cache miss.
```

Then at the `Starting workspace` phase on Coder:

```
Failed to find cached image in repository "ghcr.io/xxx/yyy". It will be rebuilt in the next apply. Error: get cached image: error probing build cache: uncached RUN command is not supported in cache probe mode
Apply complete! Resources: 2 added, 1 changed, 1 destroyed.
```

However, probing via `envbuilder` CLI directly, seems to work as expected:

```
