• Patch upgrade of REST Assured

How to test

• docker compose down --volumes && docker compose build --parallel && docker compose up --scale data-generation=0
• Sign in as admin
• Create an unpublished meta page (called "Public page" in the admin interface)
• It should not be shown at http://localhost/api/v1/meta_page when visiting in your browser
• Publish it
• It should now be present at the API
• Check if the new test does what it is supposed to do
• Check if the RLS is correct
