get podman compose up working

[pdurbin]

This is a simplification of the solution in the following pull request, intended to me merged into it:

• Support podman in demo Docker compose file IQSS/dataverse#12513

We will probably want to continue going line by line but I thought we could start with a smaller diff from develop. See https://github.com/IQSS/dataverse/compare/9731-podman2 for how small the diff from develop is. It looks like the following, as of this writing:

Here's the chatter I made while doing it: #containers > podman instead of docker @ 💬

To summarize:

• We know we don't want uid=1000,gid=1000 because Podman uses random uid's and gid's.
• We we change mode=770 to 1777 because we're writing to a tmp filesystem. This seem normal in Podman. See podman create -d --tmpfs /tmp:rw,size=787448k,mode=1777 my_image at https://docs.podman.io/en/stable/markdown/podman-create.1.html for example.
