FIX repeated game note

[Yuya-Furusawa]

Fix recursive repeated game notebook.
Original note is based on old version of Julia(ver0.X?).
I fix the note to be compatible with ver 1.3.

Great, thanks!
Can you briefly describe the major changes you made and the problems (regarding plots)?

[Yuya-Furusawa]

Major changes are:

• Change package dependencies
• Use appropriate functions instead of old functions(such as linspace)
• Fix some typos

There may be no problems in plotting graph(I will check later). There are some issues in Clp package and I opened the issue, but it is resolved.

As I see it, the plots are not displayed at nbviewer: https://nbviewer.jupyter.org/github/QuantEcon/QuantEcon.notebooks/blob/896acada3e648408d89e55c730efc7c959d35aa3/recursive_repeated_games.ipynb

Oh,
There is no problem in my local environment, but the plots are not displayed properly once I pushed it to GitHub.
The message "Unable to load WebIO. Please make sure WebIO works for your Jupyter client. For troubleshooting, please see the WebIO/IJulia documentation." comes up.
I think this issue is due to my local environment and it is resolved by pushing from another environment.

The same for me: Plots are displayed on my local computer, but not on nbviewer: https://nbviewer.jupyter.org/github/QuantEcon/QuantEcon.notebooks/blob/Yuya-Furusawa-rgnote/recursive_repeated_games.ipynb

Has this issue JuliaGizmos/WebIO.jl#381 been addressed?

@cc7768 Do you have any thought? Would it be possible to replace PlotlyJS with something else?

Sorry to intrude but I noticed this PR contains Jupyter notebook files that are hard to review on GitHub due to the JSON diffs.
