[bug] Creates a subdirectory named "artifact" under the specified path location

[lnxpy]

What happened?

This is my upload artifact step:

      - name: Upload badges as artifact
        uses: actions/upload-artifact@v3
        with:
          path: .pypi_chart/${{ matrix.package }}_badge.svg

and this is my download artifact step:

      - name: Download badges artifact
        uses: actions/download-artifact@v3
        with:
          path: .pypi_chart/
          merge-multiple: true

I expect all my .svg files to be stored under the .pypi_chart/ directory like:

• .pypi_chart/1.svg
• .pypi_chart/2.svg
• .pypi_chart/3.svg

But it creates a subdirectory called .pypi_chart/artifact/ and places those svg files there.

What did you expect to happen?

Yes @lnxpy
This is a severe bug that I experienced myself. I spent hours trying to debug before understanding that the problem was not in my code.
What's happening : when you don't specify artifact name, actions/download-artifact@v4 creates the artifact folder as you describe.

The only way to not experience this bug that I have discovered is to give a name to the artifact when uploading and downloading.

@mbriziarelli Nice. Exactly. I was struggling with it until you showed up. Wish they fix it. Another solution might be to download the artifacts in ../ and specify a directory name for the artifacts. Not sure if it works though.
