2023: Introduction

Here’s a demo introduction page. It’s created from "./_templates/YYYY-intro" as part of the call to aoc_new_year(2023).

It can be deleted with a call to aoc_delete_intro(2023) (though there needs to be at least one post in ./2023/day for the website to render from Quarto v1.4).

This is a good place to note any overarching themes for the year, what you want to practice/learn, etc.
