ci: use ANSIBLE_INJECT_FACT_VARS=false by default for testing

[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.

In order to ensure that commits and PRs conform to this, use
ANSIBLE_INJECT_FACT_VARS=false by default in our CI testing.

Update README-ostree.md if needed.

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

Summary by Sourcery

Align CI and documentation with Ansible 2.20 fact variable handling by disabling fact injection as vars and updating references to fact names.

CI:

• Set ANSIBLE_INJECT_FACT_VARS=false in qemu-kvm integration tests workflow to enforce new Ansible fact usage conventions.
• Propagate an SR_ANSIBLE_INJECT_FACT_VARS flag in the TFT workflow to control Ansible fact injection behavior during tests.

Documentation:

• Update README-ostree to reference ansible_facts["distribution"] and ansible_facts["distribution_version"] instead of deprecated fact variables.
