Add Theme parameter to toggle display of Delete my response at bottom of question pages

Would be great if there was a parameter in theme settings to toggle the div styling to show/hide the Delete my response button as detailed in: https://gitlab.com/SondagesPro/SurveyThemes/skelvanilla/-/blob/master/views/subviews/navigation/navigator_complement.twig#L8

Like "Show [Delete my Response] in footer" [Yes|No]

And if No, then include "ls-js-hidden" and if Yes, exclude it so button is displayed in footer.
