[🚀 Feature]: [dotnet] Implement high level BiDi network commands

[nvborisenko]

Description

This is a continuation of #13993

Let's think and propose good high-level API to achieve it in .NET/C#.

Have you considered any alternatives or workarounds?

Here we will adjust our collective proposal:

await using var subscription = await driver.Network.OnRequestAsync(..., new RequestOptions { WithBody = true });

await using var subscription = await driver.Network.OnResponseAsync(...);

await using var subscription = await driver.Network.OnAuthenticationAsync(...);

class Subscription(string id): IAsyncDisposable (even IDisposable?)
{
  Task UnsubscribeAsync();
}

@nvborisenko, thank you for creating this issue. We will troubleshoot it as soon as we can.

Selenium Triage Team: remember to follow the Triage Guide

This is all about events, everybody knows that native events in .NET are bad?

So I propose to start from:

var subscription = await driver.Network.OnRequestAsync(...);

[nvborisenko]

We already have

selenium/dotnet/src/webdriver/NetworkManager.cs

Line 106 in 578bc2a

public void AddRequestHandler(NetworkRequestHandler handler)

, how it correlates?..

[nvborisenko]

Last news from the field: old networking API is not under interest. New simplified API should be under Selenium namespace, meaning that it should expose types from this namespace (internally relying on BiDi implementation).
