[🚀 Feature]: [dotnet] [bidi] Rework ContinueWithAuth method

[nvborisenko]

Feature and motivation

BiDi spec: https://w3c.github.io/webdriver-bidi/#command-network-continueWithAuth

network.ContinueWithAuth = (
  method: "network.continueWithAuth",
  params: network.ContinueWithAuthParameters
)

network.ContinueWithAuthParameters = {
  request: network.Request,
  (network.ContinueWithAuthCredentials // network.ContinueWithAuthNoCredentials)
}

network.ContinueWithAuthCredentials = (
  action: "provideCredentials", 
  credentials: network.AuthCredentials
)

network.ContinueWithAuthNoCredentials = (
  action: "default" / "cancel"
)

We can apply method overload here! The example is: #15533. It is good interpretation of CDDL to .NET.

Usage example

User will call one method ContinueWithAuthAsync(...) as spec defines it, but with options how to proceed further.

New pattern determined:

network.ContinueWithAuthParameters = {
request: network.Request,
(network.ContinueWithAuthCredentials // network.ContinueWithAuthNoCredentials)
}

Meaning in .NET world it is method overload.
