Add "cs" and "python" categories to the .quiz command (and more in desc)

Relevant Issues

Closes issues #753 and #747, extends PR #726

Description

It was planned to incorporate these two categories in the same PR, however I didn't get enough quiz entries for them. But now, thanks to lak, I have enough! So in total, 60 new questions are added. I also changed the starting embed a bit to make it look nicer, made the variation tolerance stricter, and added some missing answers specified in 747 to the math & science questions.

Hey, you should test before you push, because I get this error when running the code:

Traceback (most recent call last):

The problem is most likely because you removed the { here:

@ToxicKidz I did test all 60 questions before, the error arose during the commit (copy paste error smh). It has been resolved :D

Few nitpicks here

[Kronifer]

Github seems to have added duplicate change requests, i did my best to remove them.

[Objectivitix]

@Kronifer @ToxicKidz all your changes have been implemented.

[Objectivitix]

@vcokltfre The changes will be implemented later, currently I gotta update my website lol :D
