Issue description

this documentation has several issues:
- it does not make it clear that this enum is not in the top-level namespace but in the
Pcntl namespace
- cases are broken as they all have a
Pcntl:: prefix that does not make any sense (and is invalid syntax in PHP)
Steps to reproduce
- Go to https://www.php.net/manual/en/enum.qosclass.php
Suggested fix
Cases should be rendered without the broken prefix.
For the namespace, I would suggest rendered a namespace Pcntl; statement above the enum. This seems the sensible way to render a synopsis for a namespaced enum (or class)
