refactor: handle INJECT_FACTS_AS_VARS=false by using ansible_facts instead

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
