T5Converter requires the protobuf library

I installed Kandinsky and ran `model = get_kandinsky2('cuda', task_type='text2img')`, and got the following error:

```
ImportError:
T5Converter requires the protobuf library but it was not found in your environment. Checkout the instructions on the
installation page of its repo: https://github.com/protocolbuffers/protobuf/tree/master/python#installation and follow the ones
that match your environment.
```

I entered this link, but got confused by the multitude of options. I have Windows 11 - can you tell me what exactly I need in order to run Kandinsky?
