`podman` doesn't seem to work as part of the installer generation process

As part of testing https://github.com/adoptium/installer/pull/793 I was trying to build the images using `podman` instead of docker. While the core is hard coded to invoke `docker` if I create a symlink from `docker` to `podman` on my machine somewhere at the start of the path it should work ok, and indeed the `docker build` command that the installer generation process outputs seems to work standalone. Unclear whether this is something specific to my machine or with podman itself, but worthy of investigation to look for a resolution. It's acting as though the process is squashing my `PATH` somewhere along the line but it's not lcear where that might be happening.

```

Start with the :jdk:suse:packageJdkSuse task and the Dockerfile under linux/jdk/suse/src/main/packaging. Reproduce the generated `docker build` command using the reported docker-to-podman symlink, then inspect how the process receives PATH. Done means the installer generation task can invoke the container command successfully, or the podman-specific limitation is documented.
