h3. Description

I add listener functions for both OnClientConnectedCallback() and OnClientDisconnectCallback() to update client amount when clients connect or disconnect.

Inside OnClientConnectedCallback(), the NetworkManager.Singleton.ConnectedClients.Count is correct while it's wrong inside OnClientDisconnectCallback()
h3. Reproduce Steps

1. Client: StartClient()

1. Server: OnClientConnectedCallback() gets triggered, NetworkManager.Singleton.ConnectedClientsIds has proper amount of clients which is 1

1. Client: Shutdown() or just close app

1. Server: OnClientDisconnectCallback() gets triggered, NetworkManager.Singleton.ConnectedClientsIds has WRONG amount of clients which is still 1 rather than 0

h3. Environment

• OS: macOS Sonoma
• Unity Version: 2022.3.20
