Full error text: `ErrorException: Warning: curl_multi_select(): timeout must be between 0 and 2147484`

Somehow this timeout is a negative float in some cases. I haven't been able to reproduce it manually. Here's an example:

```
ErrorException: Warning: curl_multi_select(): timeout must be between 0 and 2147484

```

Not sure if this is the place to enforce the `>=0` float or in https://github.com/symfony/symfony/blob/7.4/src/Symfony/Component/HttpClient/Response/CurlResponse.php#L363
