Closes: #475

Fixes

• The Spiral\Core\Exception\ConfigException (Btw, should we consider changing the exception for this case? So that it doesn't relate to spiral/core.) with the message to install the league/flysystem-aws-s3-v3 package is no longer thrown if the user creates an Async S3 Adapter.
• The passing of credentials has been fixed, for the Async S3 Adapter they need to be passed in a different way. Prior to these changes, there was an error:

AsyncAws\Core\Exception\InvalidArgument: Invalid option(s) "credentials" passed to "AsyncAws\Core\Configuration::AsyncAws\Core\Configuration::create". 

• The version parameter for the Async S3 Adapter has been removed, its passing causes an error:

AsyncAws\Core\Exception\InvalidArgument: Invalid option(s) "version" passed to "AsyncAws\Core\Configuration::AsyncAws\Core\Configuration::create". 

Improvements

• Added tests with Async S3 Adapter.
