Remove ferretdb (Debian LXC, no Alpine build for DocumentDB extension)

FerretDB required Debian (DocumentDB is Debian/RHEL-only, no musl build),
making it an outlier among the Alpine-based LXC creator scripts in this
repo. Dropping it leaves openbao and gitea-runner as the only LXC creator
scripts, both Alpine, which simplifies template/OS handling (see #12).

Closes #13
