[EXTERNAL] Fixing a few minor things in subjects from the RUST piscine

[TheOldestBrother]

Why?

A few student and myself found a few things that could be improved in different subjects README files, I did my best to attend to these changes.

1 - Adding a reminder of what a prime number is, a few student didn't remembered in an exam and were stuck because of that.

2 - Specifying the input type awaited by the test program to avoid a simple mistake and some frustration.

3 - Modifying the example for the nb_games : a few people struggle with this as they didn't understand that this input would determine a few other variables. I thought that with 2 examples the point would be made clearer.

Hello @TheOldestBrother!

First and foremost, do excuse us for the delay, I was just now assigned this case. We appreciate your suggestion!
I took a look at your proposition. It seems interesting, especially given that it takes into account direct feedback from students from schools.
I made some minor changes for matters of uniformity and so it's according to the master branch as is and our Prettier workflow. They'll be pushed as soon as possible. Please let me know what you think of them and do comment further on it if you have some additional feedback.

Thank you very much.

Hi @pedrodesu!

I'm sorry as well for the late reply, I had lost hope that the request would be merged but I'm happily surprised to see that it has been implemented ! (it is actually my first pull request so I hope it was okay).

I thank you all for the time you took with my suggestions and I would love to make more in the future, I think that I can still get more feedback from my fellow students that could help improve some of the projects or at least get rid of some misunderstandings that we came across.

As I'm still learning how to cooperate in this platform, I would love if you could recommend any materials that could improve my future request or maybe a guide on the specifics about cooperating in this repository. I would very much like to avoid making your work harder by making difficult requests.

Thank you very much for allowing me to be part of this change!
