ci(ansible): replace stdout_callback with result_format

The 'community.general.yaml' callback plugin has been removed. The plugin has been superseded by the option `result_format=yaml` in callback plugin ansible.builtin.default
from ansible-core 2.13 onwards. This feature was removed from collection 'community.general' version 12.0.0.
