Add a blog section to the website

Description

If there is a big announcement, an update to how we do things or something we want to talk about in length, there is only the Discord server for now. Discord is only a Chat platform, so having a blog would be more appropriate for long texts.

Todo

• Create a blog page with links to articles.
• Parse markdown and style it for the website.
• Create an article page for each Markdown file in the blog directory.
