False positive on `Generic.PHP.ForbiddenFunctions.FoundWithAlternative`

[p4veI]

Describe the bug

This sniff incorrectly reports an error while using in my case \Psl\Str\join function and reports forbidden use of the native PHP function

Code sample

src/a.php

<?php

use function Psl\Str\join;

class A {
  public function get(): string
  {
    $a = ['bar', 'baz', 'foo'];
    
    return join($a, ',');
  }
}
