feat: Flat import of markdown repo

This is a flat (without history) import of (some of) the content
from our markdown module.

We've imported this without history because the repo contains our
blog posts and showcases posts content prior to porting them to strapi.

Since this contains many images, it would balloon the size of this repo
to import the full history.

Instead, please refer to the history of the (archived) markdown repo
at: https://github.com/freesewing/markdown

+A pattern's [configuration](/reference/config/) is created by the pattern designer
+and details a number of important things about the pattern, like:
+
+ - The measurements that are required to draft the pattern
+ - The different parts in the pattern and how they depend on each other
+ - The different options that are available to tweak the pattern
