Use new confirmations endpoints

[Lyrapuff]

Apparently Steam changed how we get confirmations, this pr should make it work again, I made a few tests and it appears to be working fine, but feel free to test it yourself to make sure

I think that return Array.Empty when success==false or NeedAuthentication ==true is not a good idea. You should throw new WGTokenInvalidException when success==false or NeedAuthentication ==true. But i think return ConfirmationsResponse is better

I did some testing and it seems like Confirmation.ConfType is always MarketSellTransaction, when they are a trade offer. Fiddler shows the JSON contains

{
  "success": true,
  "conf": [
    {
      "type": 2,
      "type_name": "Trade Offer",
    }
  ]
}

The ConfirmationType enum type has MarketSellTransaction = 2 which is incorrect.

I suppose that the enum definition needs to be updated.

I used your solution and i did a temp fix for the Steam Desktop authenticator :) 🕺🏼 Basically right now i used a HttpClient instead of the browser.

I didn't commit the files from the SteamAuth repo, since im using your solution, only added more fields to the Confirmation class:

        [JsonProperty(PropertyName = "headline")]
        public string Headline { get; set; }

        [JsonProperty(PropertyName = "summary")]
        public List<String> Summary { get; set; }

        [JsonProperty(PropertyName = "accept")]
        public string Accept { get; set; }

        [JsonProperty(PropertyName = "cancel")]
        public string Cancel { get; set; }

        [JsonProperty(PropertyName = "icon")]
        public string Icon { get; set; }
