fix(meta): raise min_ansible_version to 2.11

Ansible 2.9 can neither resolve the used fully qualified collection names
reliably nor ship the community.general.sudoers module, which requires
ansible-base 2.10 or newer. Align the requirement with the sibling role
unix-users, which already declares 2.11.
