[BUG] workingdir not being used for copy

[larryclaman]

Version v2

Describe the bug

Attempting to use buildah-build action but having a problem with getting the copy command to honor the workdir. My action looks like:

    # Build container image without Dockerfile!
    - name: Build container image using Buildah 
      uses: redhat-actions/buildah-build@v2
      with:
        image:  ${{env.acrsite}}/${{env.repo}}
        tags: ${{github.run_number}} ${{ github.sha }}
        workdir: /app/
        build-args: |
          build_version=${{github.run_number}}
        base-image: mcr.microsoft.com/dotnet/aspnet:2.1
        entrypoint: |
          dotnet
          poi.dll
        envs: |
          WEB_PORT="8080"
          WEB_SERVER_BASE_URI="http://0.0.0.0"
          ASPNETCORE_ENVIRONMENT="Production"
        content: |
          myapp

What's happening is that the content from my local myapp directory is being copied into the root of the image, rather than into the /app workdir. I have tried setting workdir to /app and /app/, but in both cases, the content is copied into the root, not into the workdir. I do see that the '/app' directory was created; it's just not being used.

When looking at the run, it appears that the copy command is happening before the build config command with the workdir argument, so I think this is the cause of the problem:

@larryclaman Thanks for reporting this issue. I also think that this problem is because workingDir is being set after the copy command. Ideally, the copy command should be done after the config command if we are setting the workingDir.

We will update you once we add a fix for this.
