Major updates

The sourcehut and redis images have been updated to the most recent
versions, each running on an Alpine 3.17 base image.

The postgresql image is being held back on a version 14 image for now.

Progress on podman process

The podman process is now very mature, and some things can actually be
copied over to the original docker process.

Sourcehut now is fully functional, with possibly exception for the mail
service. Needs to be tested. Furthermore, the cron jobs should be
configured to run.

x86/aarch64 simultaneous support is also complete. See the sister repo,
huttese-apk.
