Skaffold does not rebuild derived artifact after base artifact changes

### Expected behavior
If a base artifact rebuilds, all the artifacts that depends on it should rebuild.

### Actual behavior
The base artifact is rebuild but the derived artifacts do not.
For this skaffold yaml
```
apiVersion: skaffold/v2beta26
kind: Config
metadata:
name: skaffold
build:
artifacts:
- image: docker.io/laurentiusoica/artifact1
context: artifact1
docker:
dockerfile: Dockerfile
- image: docker.io/laurentiusoica/artifact2
context: artifact2
requires:
- image: docker.io/laurentiusoica/artifact1
alias: BASE
docker:
dockerfile: Dockerfile
local:
useDockerCLI: false
useBuildkit: true
tryImportMissing: true
```

Dockerfile for base
```
FROM alpine
LABEL NAME=base
```

Dockerfile for derived image
```
ARG BASE
FROM $BASE

LABEL NAME=derived
```

Changing the base image does not trigger a rebuild on the derived image
```
