False positive UnusedVariable when casting

The (int) cast appears to cause the false positive.

I found these snippets:

https://psalm.dev/r/29407446ea

<?php

$a = random_int(0, 10) >= 5 ? true : false;

$b = (int) $a;

// This part isn't important, just using $b so there aren't more issues.
if ($b > 0) {
}

Psalm output (using commit d1398f2):

INFO: UnusedVariable - 3:1 - $a is never referenced or the value is not used

Only bool to int casts are affected.
