curl_multi_setopt() names the wrong argument when the callback given for CURLMOPT_PUSHFUNCTION is invalid: the error says argument 2 ($option), but the callback is argument 3 ($value).

To reproduce

$mh = curl_multi_init();
try {
    curl_multi_setopt($mh, CURLMOPT_PUSHFUNCTION, "not a callable");
} catch (Throwable $e) {
    echo $e::class, ': ', $e->getMessage(), "\n";
}

Before (8.4.26 and 8.5.12):

TypeError: curl_multi_setopt(): Argument #2 ($option) must be a valid callback for option CURLMOPT_PUSHFUNCTION, function "not a callable" not found or invalid function name

After:

TypeError: curl_multi_setopt(): Argument #3 ($value) must be a valid callback for option CURLMOPT_PUSHFUNCTION, function "not a callable" not found or invalid function name
