[FP] Revamp the page

[randomicecube]

It'd be cool for us to create a nice introductory page for new students coming from high school, so that they could study the basics of Python before even joining IST.

The first thing should, of course, write all the notes for the course itself. We could then have project statements for them to practice, with (ideally) an auto-grader that would work similar to "Mooshak-da-Feira" from 2020-2021 (or even a command-line one, for more advanced users).

This could also be a fun way for high school teachers who want to learn Python to learn it, since projects would probably be a fun way to keem them engaged in learning. We could go even further and, since it'd be mostly Math teachers, try to have sections dedicated to math libraries, such as Numpy and Pandas!

This is, of course, a suggestion, and nothing very urgent, but something to consider.
