Remove input data Advent of Code

[iglesias]

From https://adventofcode.com/2023/about,

Can I copy/redistribute part of Advent of Code? Please don't. Advent of Code is free to use, not free to copy. If you're posting a code repository somewhere, please don't include parts of Advent of Code like the puzzle text or your inputs. If you're making a website, please don't make it look like Advent of Code or name it something similar.

TIL! I got a Reddit notification on the phone after pushing today's [23d5] input (coincidence? Recommendations getting smarter? We'll never know):

https://www.reddit.com/r/adventofcode/comments/18an94z/psa_dont_share_your_inputs_even_in_your_github/

So, this is just a remainder: don't share your inputs, they are private and should remain so.

I force-pushed to master earlier today, living dangerously, to remove the data for today's problem. And yep, starting to use branches religiously even for this one-mens repo.

Then, I have gone through the problems from last year and found that I uploaded at least to the repo the one for the warping-cube. So, this issue is about cleaning that data nicely for respect to Advent of Code's staff and their instructions.

From master:
git filter-repo --path [AoC .in files from 2022] --invert-paths
Then, force push.
