Tutor only work on Debian-based machines

We have an override that mounts /etc/ssl/certs from the host system, required for proxying js-components as that needs the /etc/ssl/certs/ca-certificates.crt file.

However on my machine (i use arch btw) ca-certificates.crt points to ../../ca-certificates/extracted/tls-ca-bundle.pem which is outside /etc/ssl/certs, and we probably don't want to include the whole /etc/ssl either.

Two solutions:

1. Install ca-certificates on the nginx image. Since tutor doesn't allow for such customization, this is kind of out of the way.
2. Let Caddy handle the forwarding. It has the CA certificates by default. Plus, it will remove a middle man.
