* fix: enforce minimum version of docker/podman
This allows to always pass `--platform` to the OCI engine
thus fixing issues with multiarch images.
* Allow older versions with warnings
* Upgrade docker on Travis CI
* fix: use `docker cp` instead of `tar`
* Enforce docker>=24.0
* move log to include container.copy_into
* fix: travis-ci, only update docker on aarch64
* skip test_multiarch_image on s390x / ppc64le
* skip flaky test
* chore: only install test deps on Travis CI
* fix: do not try to pull images tagged `cibw_local`
* use "--pull=never" for local images
* Use docker image inspect to check if an image needs to be pulled
