* Reverted the removal of the method parameter, and added changelog fragment

* Update changelogs/fragments/1867-modhelper-cmdmixin-dict-params.yml

Co-authored-by: Felix Fontein <felix@fontein.de>

* Update plugins/module_utils/module_helper.py

Co-authored-by: Felix Fontein <felix@fontein.de>

For array mode, use a list of types.

version_added: 1.0.0
disable_facts:
description:
- For backward compatibility, output results are also returned as C(ansible_facts), but this behaviour is deprecated
and will be removed in community.general 4.0.0.
- This flag disables the output as facts and also disables the deprecation warning.
