* Add new doc parsing backend script which more efficiently dumps all necessary data about collections and plugin docs. * Use new script instead of ansible-doc. * Make sure that proper JSON serialization is used. * Make doc parsing backend configurable. * Improve filtering. * Equivalent to ansible/ansible#72359. * Change default backend to ansible-internal.
