Fix Social SDK leaving lobby

[thiagola92]

In the section Managing Lobbies, the code for Leaving a Lobby:

// Leaving a lobby from the client
client->LeaveLobby(01234567890, [](discordpp::ClientResult result, uint64_t lobbyId) {
  if(result.Successful()) {
    std::cout << "🎮 Left lobby successfully! Lobby Id: " << lobbyId << std::endl;
  } else {
    std::cerr << "❌ Leaving lobby failed\n";
  }
}

Mention a uint64_t lobbyId which doesn't seem to exist in LeaveLobbyCallback.

I was thinking in changing the example to:

// Leaving a lobby from the client
client->LeaveLobby(01234567890, [](discordpp::ClientResult result) {
  if(result.Successful()) {
    std::cout << "🎮 Left lobby successfully! Lobby Id: 01234567890\n";
  } else {
    std::cerr << "❌ Leaving lobby failed\n";
  }
}

Totally off the top of my head:

// Leaving a lobby from the client
uint64_t lobbyId = 01234567890;
client->LeaveLobby(lobbyId, [&](discordpp::ClientResult result) {
  if(result.Successful()) {
    std::cout << "🎮 Left lobby successfully! Lobby Id: " << lobbyId << std::endl;
  } else {
    std::cerr << "❌ Leaving lobby failed\n";
  }
}

But I think that will work, and you can see it get passed through? WDYT?

I like it.

In this case, I could also change the example from Sending Messages to a Lobby to match it:

uint64_t lobbyId = 01234567890;

client->SendLobbyMessage(lobbyId, "Hello", [](discordpp::ClientResult result, uint64_t messageId) {
  if(result.Successful()) {
    std::cout << "📨 Message sent successfully!\n";
  } else {
    std::cerr << "❌ Message sending failed\n";
  }
});

Note: can I also add a space between creating variable and the function calling?

Sure - that works for me 👍🏻 sounds good!

No concerns on extra line break 😄
