Test instructions for the acceptance test before the PR gets merged

This PR can be acceptance tested by following these steps:

Note: The below are no longer relevant, because of #22661.

• Install and activate Yoast SEO for the first time in your site (or deactivate Yoast on your existing site and then manually delete from the db all wpseo options and then activate the plugin)
• Log in with a different user and confirm that you see the topbar and sidebar notifying that you have at least one notification
• Go to the alert center and confirm that you see this alert:

• The link there points to https://yoa.st/new-admin-newsletter-sign-up along with the usual shortlink parameters.
• The dismiss button will refresh the page and hide that alert forever
• If you want to make the alert re-appear, delete the wpseo-ping-other-admins_resolved usermeta for that user
• Create a new admin (or SEO manager) and repeat the test
  • At the end of the tests, resolve the new alert and confirm that for any other admins, the alert still displays.
• In a fresh site, install/activate via WP CLI (run wp plugin activate wordpress-seo)
  • The feature will not work, but the plugin activation went without problems
  • which means that no user will see that alert ever, no matter new or old.
  • check the first_activated_by setting in the wpseo option and confirm that it is equal to zero.
• In a fresh site, install Yoast SEO normally and with the same user confirm that you dont see the new alert ever.
