Adds an admin sub-menu that lists pages that haven't been updated on a year or more.
Then, you can check whether these pages receive links from other contents on the site, or are present on a navigation menu.
It allows easy deletion of individual or a bunch of pages.
Install with composer.
Get js dependencies and build the vue client used for the admin panel with:
yarn install && npx encore production
Go to your WordPress admin panel and search within the "Pages" menu.
