Can't use `empty`, `isset`, `unset` as method names

[pchapl]

Describe the bug
When empty (or isset, unset) is used as method name, phpcs doesn't recognize it and produce weird error messages

Code sample

<?php

declare(strict_types=1);

namespace App;

abstract class Temp
{
    abstract public function empty(): void;
    abstract public function isset(): void;
    abstract public function unset(): Temp; // <- another error for CamelCased return type
}

To reproduce

1. Create a file called Temp.php with the code sample above...
2. Run phpcs Temp.php ...
3. See error message displayed

FILE: Temp.php
----------------------------------------------------------------------
FOUND 4 ERRORS AFFECTING 3 LINES
----------------------------------------------------------------------
  9 | ERROR | Expected "function abc(...)"; found "function abc(...)"
 10 | ERROR | Expected "function abc(...)"; found "function abc(...)"
 11 | ERROR | Method name "Temp::Temp" is not in camel caps format
 11 | ERROR | Expected "function abc(...)"; found "function abc(...)"
----------------------------------------------------------------------

Expected behavior
No errors OR message about inappropriate method name

Versions (please complete the following information):

• OS: Linux 5.17.12-200.fc35.x86_64
• PHP: 8.1.7
• PHPCS: 3.7.0
• Standard: PSR12

Seriously ? Duplicate of #3609 (and #3611 and #3612 and #3613), which has already been fixed via #3610.

My bad: didn't realize that default search condition includes open issues only. Sorry!
