The partial_fit method of TimeSeriesRegressor is deprecated, but is still used in 2 files of the documentation:

• plot_timeseries_enbpi.py
• ts-changepoint.ipynb

We should

• update those file using the new update method
• give a version number for actual deprecation. Because this method has been deprecated for a while, rather than deprecating it in 2 minor versions (as per sklearn guidelines), I suggest deprecating it in the next minor version.
