Fixes for Outdated Client and Send Message Errors

[jonas-is-coding]

This pull request addresses two main issues encountered in the whatsapp-gpt project:

1. Outdated Client Error: Updated the Go packages to resolve issues with WebSocket connection errors caused by an outdated WhatsApp client.
2. Send Message Error: Modified the message-sending logic to comply with the latest WhatsApp package syntax and ensure proper message delivery.

---

Changes Made:

1. Updated Packages:

   • Upgraded all Go packages to resolve the "Client outdated" error during WebSocket connection.

2. Message Sending Fix:

   • Updated the SendMessage method usage to fit the new syntax of the WhatsApp package. This ensures the bot can successfully send responses.

Code Example:

Before:

mycli.WAClient.SendMessage(context.Background(), userJid, "", response)

After:

_, err = mycli.WAClient.SendMessage(context.Background(), userJid, response, whatsmeow.SendRequestExtra{})
if err != nil {
    fmt.Println("Error sending message:", err)
}

Testing Instructions:

1. Clone the repository and navigate to the project directory.
2. Update and install the required Go packages:

   go mod tidy
   go get -u ./...

3. Ensure the chatbot API is running (e.g., using python server.py).
4. Run the project:

   go run main.go
