Access test run images

When using the open source edition of Lost Pixel, you might want to look at your failed tests that were happening on CI. While Lost Pixel provides extensive logging, you would not be able to see the images in the output of the action by default. To access the generated images you would need to use GitHub Actions Artefacts. Presuming you did not change the relative paths to the images extend GitHub action with the following step that takes place after lost-pixel:

...

  - uses: actions/upload-artifact@v3
    with:
      name: lost-pixel-artefacts
      path: .lostpixel

This step will ensure that everything that will be generated during the Lost Pixel action run on CI will be accessible for the download later after the workflow is finished:
