Good fixes, thank you!

I corrected the now added support for Conditional seasonality to be included.

Further, I think we can drop
https://github.com/ourownstory/neural_prophet/blob/fix-prophet-tutorial/docs/source/how-to-guides/changes-from-prophet.md
Do you mind quickly checking if it's contents are contained within this guide?
(feel free to merge this and remove it in a separate PR)

Finally, I remember we also had a tutorial for moving from prophet to NeuralProphet (not just TorchProphet). I just checked, but could not resurface it quickly again. However, it is the more important of the two, and we should revive it if anyhow possible.
