Extra docs: generate Ansible outputs with 'antsibull-docs ansible-output' (#10421)

* Generate many Ansible outputs with 'antsibull-docs ansible-output'.

* Generate YAML output as well.

* Check ansible-output from CI instead of updating.

* Use reset-previous-blocks meta action; generate more code blocks.

* Use set-template meta action.

* Run ansible-output in CI if anything in docs/ is changed.

* Remove unnecessary allow_duplicate_keys.
