forecasting growth example dataset looking very different from documentation

in the Prophet documentation there's an example on forecasting growth using a cap value, linking to the `example_wp_log_peyton_manning.csv` dataset:
https://facebook.github.io/prophet/docs/saturating_forecasts.html#forecasting-growth

When I run this example, I get a very different time series..

This is what is in the online documentation:

```
df <- read.csv('https://raw.githubusercontent.com/facebook/prophet/main/examples/example_wp_log_peyton_manning.csv')
df$cap <- 8.5
m <- prophet(df, growth = 'logistic')
future <- make_future_dataframe(m, periods = 1826)
future$cap <- 8.5
fcst <- predict(m, future)
plot(m, fcst)
```

and this is what i get when i run that exact same code:


Has there been a change in the dataset on github since the document was rendered?
