When using a literal negative number as param type, Psalm doesn't recognized it throwing an error.

I found these snippets:

https://psalm.dev/r/9aa91865eb

<?php

namespace n;

class Foo {
    /**
     * @param -1|0|1 $i
     */
    public static function takeValue($i): int {
        return $i;
    }
}

Psalm output (using commit 2c77424):
