BC-8763 workaround for actions/build-push-action@v6

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
