Alamofire 5: Incorrect documentation instructions for default HTTP headers

[hardev]

• I've read, understood, and done my best to follow the *CONTRIBUTING guidelines.

The documentation has this paragraph which talks about a non existing property of URLSessionConfiguration

If you need to customize these headers, a custom URLSessionConfiguration should be created,
the defaultHTTPHeaders property updated, and the configuration applied to a new Session instance.
Use URLSessionConfiguration.af.default to customize your configuration while keeping Alamofire's default headers.

What did you do?

let configuration = URLSessionConfiguration.af.default
configuration.defaultHTTPHeaders

What did you expect to happen?

I expected the defaultHTTPHeaders property to be present in the configuration

What happened instead?

Got an Xcode error saying Value of type 'URLSessionConfiguration' has no member 'defaultHTTPHeaders'
