Fix cannot build Docker images using Podman Compose

[kianmeng]

This PR resolves the following error when using podman-compose:

Error: short-name "caddy:2.6.4-alpine" did not resolve to an alias and
no unqualified-search registries are defined in
"/etc/containers/registries.conf"

We also bump the Docker image for Caddy and Alpine Linux.

@whatyouhide Not sure why, I kept getting this two test cases that failed on me, but these tests are pointing to localhost?

podman-compose up --force-recreate -d
mix test

I disabled the DNS adblocker, which seemed to work. Not sure why the adblocker was aggressively blocking localhost as well.
