Plotly FigureWidget plots do not show in docs

...There we go again 😭

Only one JS library missing 😉

Back in black:

• The Cowell notebook has a JS syntax error because of an apostrophe https://docs.poliastro.space/en/stable/examples/Propagation%20using%20Cowell's%20formulation.html
• The notebooks in latest do not show any plots, see for instance https://docs.poliastro.space/en/latest/examples/Plotting%20in%203D.html

It seems that the plots are back, and without weird CSS issues... I really don't know what happened in between. Anyway, I will fix the apostrophe, and in the meanwhile close this issue... Until next time.
