Missing TaintedSql when calling mysqli::execute_query

[cgocast]

The following code should trigger two TaintedSql issues : https://psalm.dev/r/f98b88f1aa

I'll write a PR that fixes this bug

I found these snippets:

https://psalm.dev/r/f98b88f1aa

<?php //--taint-analysis

$userId = $_GET["user_id"];
$query = "delete from users where user_id = " . $userId;

$link = mysqli_connect("localhost", "my_user", "my_password", "world");
$result = mysqli_execute_query($link, $query);  // Should trigger a TaintedSql

$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$result = $mysqli->execute_query($query);  // Should trigger a TaintedSql

Psalm output (using commit 16b24bd):

No issues!
