🚀 Feature: Update appwrite package

### 🔖 Feature description

The appwrite package used in this playground is quite old.

### 🎤 Pitch

The package should be updated so it can easily be run against cloud.

In addition, the endpoint should be defaulted to cloud.

Nenhum arquivo ou teste é mencionado na issue. Comece localizando a declaração de dependência do Python e a configuração do endpoint do Appwrite e, em seguida, verifique como os exemplos do playground inicializam o cliente. Considera-se concluído quando o pacote estiver atualizado e o endpoint apontar por padrão para o Appwrite Cloud.
