Error while deploying with rootless podman

Podman (rootless) was throwing an error while I was trying to deploy owntracks with the official image:

Error: open `.../.local/share/containers/storage/overlay/.../merged/.containerenv`: No such file or directory: OCI runtime attempted to invoke a command that was not found

So I tried to build the image myself but I encountered another error:

$ git clone https://github.com/owntracks/docker-recorder && cd docker-recorder
$ podman build --tag owntracks-local -f ./Dockerfile

I didn't notice anything that could potentially cause this error within the Dockerfile. So I updated the alpine image version to 3.16 and ran the build again, which seems to fix the issue.

$ podman build --tag owntracks-local -f ./Dockerfile

I haven't tested it with Docker, but I'm leaving this in case anyone's using Podman.
