Resolve static in assert phpdoc

Closes phpstan/phpstan#12548

I didn't exactly copy-paste the snippet given because I don't understand how you can expect

/**
     * @template T of object
     *
     * @param T $object
     *
     * @return (T is static ? T : static)
     *
     * @phpstan-assert-if-true =static $object
     */
    public static function assertInstanceOf(object $object)
    {
        if (!$object instanceof static) {
            throw new \Error('Object is not an instance of static class');
        }

        return $object;
    }

to correctly work: phpstan-assert-if-true only work if the method returns a boolean.

Aren't both phpstan/phpstan#11289 and phpstan/phpstan#12376 fixed too?

Indeed, I added non regression tests
