Update readme for the Python Model

Hi,
I see that there is comment in the python module, where instead of transformer model the hybrid model is commented.
So just fixing the small issue.

Current
```
# model = Zonos.from_pretrained("Zyphra/Zonos-v0.1-hybrid", device="cuda")
model = Zonos.from_pretrained("Zyphra/Zonos-v0.1-transformer", device="cuda")
```

Changes to

```
model = Zonos.from_pretrained("Zyphra/Zonos-v0.1-hybrid", device="cuda")
# model = Zonos.from_pretrained("Zyphra/Zonos-v0.1-transformer", device="cuda")
```
