feat: add webhooks

[null8626]

The following pull request is a toned down version of #29. This pull request focuses solely on adding a webhooks wrapper for ASP.NET Core/Blazor.

This is not how a ASP.NET Core webhook endpoint should look like. Prefer using the minimal API to create a route at build-time. This will let the internal ASP.NET core router handle all of the actual context.

public static class RoutingExtension {
  public static void UseVoteWebhook(IRouteEndpointBuilder router, string path, ...) {
    router.MapGet(path, (req) => {
      ...
    });  
  }
}

Will work on it.

Done. Made it more similar to Node.js SDK' webhooks wrapper.

Example usage:

using DiscordBotsList.Api.Webhooks;

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

app.MapGet("/", () => "Hello World!");

var webhooks = new Webhooks("my webhook secret");

app.MapPost("/webhooks", webhooks.Listener((context, vote) =>
{
    Console.WriteLine($"A user with the ID of {vote.VoterId} has voted us on Top.gg!");

    return Task.CompletedTask;
}));

app.Run();

looks good to me

Most of this wouldn't work with the actual api. Refer to the docs here for more information.

This can be done without an allocation an hmac object every request by using

HMACSHA256.HashData(authorization, data);

[null8626]

Done. See this commit.

[velddev]

This would break on additional other values. See; https://docs.top.gg/docs/API/v1/webhooks/

Done. What do you think of this diff?

[velddev]

Wrong Type, this is the legacy payload

[null8626]

Done. Check this diff.

So sorry! I was too fixated on top-gg/webhooks-v2-nodejs-example that I didn't notice the new webhook events. My bad. I've addressed them now.
