Move all artifacts into 'wheels'

I think something is wrong in the release workflow when downloading artifacts:

In polars_istr, we have name: wheels

 release:
    name: Release
    runs-on: ubuntu-latest
    if: "startsWith(github.ref, 'refs/tags/')"
    needs: [linux, windows, macos, sdist]
    permissions:
      id-token: write
    environment: release
    steps:
      - uses: actions/download-artifact@v4
        with:
          name: wheels
      - name: Publish to PyPI
        uses: PyO3/maturin-action@v1
        with:
          command: upload
          args: --non-interactive --skip-existing *

But in polars_ds, I am using a pattern here pattern: wheel-*

  release:
    name: Release
    runs-on: ubuntu-latest
    if: "startsWith(github.ref, 'refs/tags/')"
    needs: [build-wheels, create-sdist]
    permissions:
        id-token: write
    steps:
      - uses: actions/download-artifact@v4
        with:
          pattern: wheel-*
          merge-multiple: true

      - uses: actions/download-artifact@v4
        with:
          pattern: sdist-*
          merge-multiple: true
          
      - name: Publish to PyPI
        uses: PyO3/maturin-action@v1
        with:
          command: upload
          args: --non-interactive --skip-existing *
