Symfony version(s) affected: 5.2.6

Description
I get the following warning and notice:

User Warning: Configure the "curl.cainfo", "openssl.cafile" or "openssl.capath" php.ini setting to enable the CurlHttpClient
User Notice: Upgrade the curl extension or run "composer require amphp/http-client" to perform async HTTP operations, including full HTTP/2 support

I am on Windows and don't have these options set in my php.ini, but I have set cafile

How to reproduce

• on Windows, enable the curl PHP extension. Don't set any options in php.ini.
• create a symfony app, add symfony/http-client
• get a valid certificate in PEM format
• edit app/config/packages/framework.yaml, set http_client -> default_options -> cafile: <path to PEM file>
• inject HttpClientInterface, perform a request

Possible Solution
I guess this check in HttpClient::create is faulty:
if ('\\' !== \DIRECTORY_SEPARATOR || ini_get('curl.cainfo') || ini_get('openssl.cafile') || ini_get('openssl.capath'))

Extending it with isset($defaultOptions['cafile']) || isset($defaultOptions['capath']) fixes both log messages.
However, CurlHttpClient can also be used if you set cafile or capath on options for scoped clients, but these options aren't available in the factory.

Why is this check present anyway? CurlHttpClient works great on Windows without any of these options.
