Debops 3.0.3 not compatible with latest ansible

Hi,

I'm reporting that debops 3.0.3 (installed from galaxy-collections) is not compatible with latest ansible installed via ppa ( https://docs.ansible.com/ansible/latest/installation_guide/installation_distros.html#installing-ansible-on-ubuntu ) on Ubuntu 22.04 .
Ferm playbook (~/.ansible/collections/ansible_collections/debops/debops/playbooks/service/ferm.yml) fails with Jinja templating error, string was expected, but got int.

Using ansible from official Ubuntu repos (non-ppa) do not cause this issue, but that ansible version is EOF.

OS: Ubuntu 22.04
Debops: 3.0.3 (from galaxy-collections)

Ansible version from official Ubuntu repos:

$ ansible --version
ansible 2.10.8
  config file = /home/ansible/debops/ansible.cfg
  configured module search path = ['/home/ansible/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.10.6 (main, Nov 14 2022, 16:10:14) [GCC 11.3.0]

Ansible version from ppa:

$ ansible --version
ansible [core 2.13.7]
  config file = /home/ansible/debops/ansible.cfg
  configured module search path = ['/home/ansible/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3/dist-packages/ansible
  ansible collection location = /home/ansible/.ansible/collections:/usr/share/ansible/collections
  executable location = /usr/bin/ansible
  python version = 3.10.6 (main, Nov 14 2022, 16:10:14) [GCC 11.3.0]
  jinja version = 3.0.3
  libyaml = True

Reproduce the failure on Ubuntu 22.04 with DebOps 3.0.3 and Ansible core 2.13.7, using playbooks/service/ferm.yml under the DebOps collection path. Inspect the reported Jinja templating failure and compare it with Ansible 2.10.8. Done means the ferm playbook runs without the reported type error on the newer Ansible version.
