💻 New slides

Fixes #4960
Fixes #4932
Fixes #5056

Let me know if the Achievements part is correct, it is difficult to test and I don't have a lot of experience with them yet.
How to test

1. Go to /for-teachers, open a slides level
2. Run a program for which you would get an achievement and make sure no achievement is shown
3. Test the language switcher
4. Test slides look good

@Annelein remember when we were fixing the code together and talked about the fact that the switcher should change the keywords? I don't see them changing yet!

Wow I knew there was something I was missing, totally forgot about it, will do it next week!

@hasan-sh I think this has to do with slide['code'] which is not being updated properly. Could you help me out?

@hasan-sh uuuh what is happening, it's not working anymore? haha

It is for me! What do you see happening?

[hasan-sh]

@Annelein i fixed it, probably you meant the tests! It's because window.top.reload() was reloading the cypress window when we click on that button.

@hasan-sh I think it is then ready to be reviewed again right?
