PHP deprecation warning(s) triggered by `Utils\http_request()`

Bug Report

Describe the current, buggy behavior

I'm getting further deprecation warnings with PHP 8.1.x+ triggered by failed calls to Utils\http_request():

Deprecated: Exception::__construct(): Passing null to parameter #2 ($code) of type int is deprecated in phar:///path/to/wp-cli.phar/vendor/wp-cli/wp-cli/php/utils.php on line 826
Fatal error: Uncaught WpOrg\Requests\Exception: cURL error 28: Operation timed out after 10004 milliseconds with 0 bytes received in /path/to/httpdocs/wp-includes/Requests/src/Transport/Curl.php:490

The second parameter of the class constructor for RuntimeException is defined as being of type int yet null is being passed in both cases inUtils\http_request().

Describe how other contributors can replicate this bug

When running PHP 8.1.x+, call Utils\http_request( 'https://example.domain.fails' ).

Provide a possible solution

Passing (int) 0 avoids the warnings:

throw new RuntimeException( $error_msg, 0, $exception );

PR to follow shortly.
