Default timeouts are set to zero, instead of 30 seconds

Hey Guys,

Here https://codeception.com/docs/modules/WebDriver Codeception claims, that default timeouts (`connection_timeout` and `request_timeout`) are 30 seconds. Because of the bug, I think they are set to 0 now, which makes curl_exec() later to wait indefinitely.

Check this code https://github.com/Codeception/module-webdriver/blob/master/src/Codeception/Module/WebDriver.php#L362
```
$this->connectionTimeoutInMs = $this->config['connection_timeout'] * 1000;
$this->requestTimeoutInMs = $this->config['request_timeout'] * 1000;
```
by default both values are `null`, but multipling `null * 1000` results in `0`, not `null`. Later here https://github.com/php-webdriver/php-webdriver/blob/main/lib/Remote/RemoteWebDriver.php#L101 it is strictly compared with `null`, but since the value is `0` it passes the condition and sets timeout to `0` which makes curl to wait indefinitely.

从 src/Codeception/Module/WebDriver.php 约第 362 行开始，检查 connection_timeout 和 request_timeout 的默认值是如何转换的。将该行为与文档中说明的 30 秒默认值，以及 php-webdriver 的 lib/Remote/RemoteWebDriver.php 约第 101 行处的 null 检查进行比较。完成的标准是，省略的超时设置不再变为零，也不会导致 curl_exec() 无限期等待。
