Push to heroku registry fail - 405 Method Not Allowed

[luca-montaigut]

Hello, a buildkit update prevents pushing on the heroku registry.

Here's what I got from support: https://help.heroku.com/74S3XXMP/workaround-for-docker-push-error-405-method-not-allowed-using-buildkit-0-11

It seems that the problem comes from the "provenance" option. I don't know if I can do anything else to help but I thought I could at least get you the information.

Temporary fix, update setup-buildx action :

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v2
        with:
          version: v0.9.1

Hello! It would be great to have a way to disable provenance attestation on the configuration. I tried to use the env variable BUILDX_NO_DEFAULT_ATTESTATIONS but it didn't work for me. Any idea other than to downgrade buildx?
