The configure link points to '#configure' => 'redirect_404.ignore_404', but this is nonsense because that path is for adding a path to redirect 404 ignore list.
Install the checklist and redirect 404 and try to use the link...
Change it to redirect_404.fix_404 - which is the configure link from the redirect 404 module...
name: 'Redirect 404'
type: module
description: 'Logs 404 errors and allows users to create redirects for often requested but missing pages.'
core_version_requirement: ^9.2 || ^10 || ^11

Encountered this while writing documentation for SEO Checklist for Drupal CMS. Fix looks good; manually tested on a Drupal CMS site. Reapplying the SEO Tools recipe fixes the Configure link under Configure the Redirect 404 module in the Clean URLs section.
