False positive: ini_set error when value is not string

[mdeweerd]

According to the PHP documentation, ini_set allows simple types for the $value argument:
https://www.php.net/manual/en/function.ini-set.php

But phan complains when the value is a float for instance.

Phan 5.4.2
php-ast version 1.0.16
PHP version used to run Phan: 8.1.13

Test file:

<?php
ini_set("A","1");
ini_set("B",1);
ini_set("C",1.0);
ini_set("D",true);
ini_set("E",false);
ini_set("F",null);
