Primero prueba con `bump-pydantic`; si tus tests pasan y eso funciona, entonces terminaste con un solo comando. ✨

Un proceso similar se aplicaría a cualquier otro programa de servidor ASGI.

/// tip | Consejo

Al añadir `standard`, Uvicorn instalará y usará algunas dependencias adicionales recomendadas.
