Fix for editing settings with simple form and rails 7.1

related to heartcombo/simple_form#1834
The previous html for editing a setting looked like this:

<input class="string optional form--medium enhanced" type="text" name="setting[setting[36086]][value]" id="setting_setting_70243__value">

it now looks like:

<input value="Job position" class="string required form--medium enhanced" type="text" name="setting[setting_36086][value]" id="setting_setting_36086_value">
