:sparkles: add plotly-resampler as plotting engine

[jvdd]

This PR adds "plotly-resampler" as option for the plotting engine of StatsForecast.plot method, see #342

Would love to hear your feedback on this!

Example use of plotly-resampler (in the ElectricityLoadForecasting.ipynb notetbook)

Note that plotly-resampler properties can be passed in the resampler_kwargs argument. :arrow_down: illustrates how for example the number of shown samples can be changed!

StatsForecast.plot(df, engine="plotly-resampler", resampler_kwargs={"default_n_shown_samples": 3000, "show_dash": {"mode": "inline"}})

PS: also fixed a minor typo in the CONTRIBUTING.md file

I'm not sure why the macOS - Python 3.8 CI is stuck at the Run ray step in this pull request. It looks like the same issue occurred in #358 as well.

Not really sure if this is related to the macOS test hanging, but GitHub is performing some maintenance on their macOS virtual environments
