Offering to co-maintain Simple Style Guide

Problem/Motivation

I use this module to generate a styleguide for using unCSS for a couple sites I maintain. This is an important module for my sites, so I would like to offer to co-maintain the module.

There are several issues that have been awaiting approval.

• 📌 Add GitLab CI template Needs review
• 🐛 Need accessCheck for entity queries Needs review
• 📌 Automated Drupal 11 compatibility fixes for simple_styleguide Needs review

If you allow me to be a co-maintainer, I will:

* Adopt GitLab CI and fix the tests
* Release a Drupal 11 compatible version
* Clean up the issue queue

I have recently done similar work for the Rename Admin Paths and Alternative
User Emails modules.

Thank you for your consideration.
