This syntax is [supported in docker/buildkit stack](https://www.docker.com/blog/new-dockerfile-capabilities-v1-7-0/) but I couldn't find that it is supported in podman/buildah stack. Locally I have Buildah 1.39 and in CI it's 1.33. I checked https://buildah.io/releases/ but nothing mentioned "variable expansions" in release notes from 1.33 to 1.39, so I have generally no idea how it works locally.
