Use steam id of the game owner

To cope with ban evading through steam family share.

Alternatively we can kick people using family-shared account. Here chat gpt code doing that:

using System;
using System.Net.Http;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        // Replace <STEAM_API_KEY> with your actual Steam API key
        string apiKey = "<STEAM_API_KEY>";

        // Replace <STEAM_ID> with the Steam ID of the user you want to check
        string steamId = "<STEAM_ID>";

        // Replace <APP_ID> with the Steam App ID of the game you want to check ownership of
        int appId = <APP_ID>;

        // Construct the URL to call the "GetOwnedGames" API method
        string url = $"http://api.steampowered.com/IPlayerService/GetOwnedGames/v0001/?key={apiKey}&steamid={steamId}&format=json&include_appinfo=1";

        // Create an HttpClient instance to make the API call
        using (HttpClient client = new HttpClient())
        {
            try
            {
                // Make the API call and get the response
                HttpResponseMessage response = await client.GetAsync(url);
                response.EnsureSuccessStatusCode();

                // Read the response as a string
                string responseBody = await response.Content.ReadAsStringAsync();

                // Parse the JSON response into a dynamic object
                dynamic json = Newtonsoft.Json.JsonConvert.DeserializeObject(responseBody);

                // Check if the user owns the specified game and is not sharing it with family members
                foreach (var game in json.response.games)
                {
                    if (game.appid == appId && !game.is_shared)
                    {
                        Console.WriteLine($"User {steamId} owns game {appId}");
                        return;
                    }
                }

                Console.WriteLine($"User {steamId} does not own game {appId}");
            }
            catch (HttpRequestException ex)
            {
                Console.WriteLine($"An error occurred while calling the Steam API: {ex.Message}");
            }
        }
    }
}

Bannerlord may depend on Steamworks.NET so we could use that library instead of crafting the request.
