ini_file unable to add / replace whole section #10287
Description
Summary
Documentation at https://docs.ansible.com/ansible/latest/collections/community/general/ini_file_module.html for option parameter says
If set (required for changing a value, this is the name of the option.
May be omitted if adding/removing a whole section
However, leaving option unset does not work for setting a whole section instead resulting in an error. Somebody else ran into a similar problem at https://serverfault.com/questions/969137/ansible-ini-file-module-replace-whole-section
