Build summary shows all images with name docker

[mrfelton]

H,
I'm building multiple apps from a bake file and the build summary in GHA shows them all with the name docker, which makes it not very useful since I don't know which build summary relates which app.

Some info about my setup:

1. All apps use the same context
2. All apps use the same dockerfile, but with different build args
3. The bake is invoked like this

    - name: 'Setup Buildx'
      uses: docker/setup-buildx-action@988b5a0280414f521da01fcc63a27aeeb4b104db # [email protected]
      with:
        buildkitd-config-inline: |
          [worker.oci]
            # More than 6 parallel builds can cause OOM on our big runners.
            max-parallelism = 6

    - name: 'Docker metadata'
      id: meta
      uses: docker/metadata-action@8e5442c4ef9f78752691e2d8f8d19755c6f78e81 # [email protected]

    - name: 'Build and push'
      uses: docker/bake-action@76cc8060bdff6d632a465001e4cf300684c5472c # [email protected]
      env:
        TAG: ${{ inputs.tag }}
      with:
        workdir: docker
        load: false
        targets: ${{ steps.sanitize-projects.outputs.projects }}
        push: ${{ inputs.push }}
        files: |
          ./docker-bake.json
          ./docker-bake.override.json
          ${{ steps.meta.outputs.bake-file-labels }}
          ${{ steps.meta.outputs.bake-file-labels }}

An excert from the bake file:

    "example-app-admin": {
      "inherits": [
        "zapgeneric"
      ],
