fix: sudo with YNH 11.1+

Since YNH 11.1+, admins group is integrated with YNH and is part of sudoers. Our own deployment could be problematic, particularly with sudo in common.yml:

# https://galaxy.ansible.com/weareinteractive/sudo
sudo_package: null
purge_other_sudoers_files:    no
sudo_users:
  - name:                     "%{{ admin_group }}"
    nopasswd:                 yes
