Builder ignoring --test arg in BUILD_ARGS

[ChrisRomp]

On push to main the CI is attempting to upload the image to a Docker repository, but my add-on builds locally so I don't store the built images. This used to work but one of the updates Dependabot helpfully added for the Builder action caused it to not work on my latest release (I haven't released in a while, so I'm not sure at which version this changed).

Expected result: Having --test in BUILD_ARGS would cause the Action to not try and upload the image.

Here's my CI YAML (truncated -- full config is here ):

name: Builder

env:
  BUILD_ARGS: "--test"
  MONITORED_FILES: "build.yaml config.yaml Dockerfile app"

...

      - name: Build ${{ matrix.addon }} add-on
        if: steps.check.outputs.build_arch == 'true'
        uses: home-assistant/builder@2024.03.5
        with:
          args: |
            ${{ env.BUILD_ARGS }} \
            --${{ matrix.arch }} \
            --target /data/${{ matrix.addon }} \
            --image "${{ steps.check.outputs.image }}" \
            --docker-hub "ghcr.io/${{ github.repository_owner }}" \
            --addon

The error at the end of the build:

I wasn't able to reproduce the issue, and at least when looking at this log it seems to work with the linked config (v1.0.1)? 🤔
