refactor: handle INJECT_FACTS_AS_VARS=false by using ansible_facts instead

[richm]

Ansible 2.20 has deprecated the use of Ansible facts as variables. For
example, ansible_distribution is now deprecated in favor of
ansible_facts["distribution"]. This is due to making the default
setting INJECT_FACTS_AS_VARS=false. For now, this will create WARNING
messages, but in Ansible 2.24 it will be an error.

See https://docs.ansible.com/projects/ansible/latest/porting_guides/porting_guide_core_2.20.html#inject-facts-as-vars

Summary by Sourcery

Update role variables and test playbooks to use ansible_facts-based access instead of deprecated fact variables.

Enhancements:

• Replace deprecated direct fact variables (e.g. ansible_distribution, ansible_os_family, ansible_default_ipv4) with ansible_facts lookups across role vars and test tasks to align with Ansible 2.20+ behavior.

Tests:

• Adjust test tasks and test variable files to reference facts via ansible_facts to prevent deprecation warnings and future errors in newer Ansible versions.
