BC-8763 workaround for actions/build-push-action@v6 (#5452)

as it appears to be incompatible with actions/download-artifact@v4 /cloudposse/github-action-matrix-outputs-read#29 (comment)
see docker/build-push-action#1167

in short if one downloads an artifact that is not of type zip it might/will fail to download so most of the times this actions/toolkit#1874 might resolve the whole mess
