Fix SEO
Improve SEO. Now meta tags are generated with:
- title and description from _config.yml
- title of the article
- tags provided in the article.
An example SEO meta tag with all that would be this:
<meta name="description" content="Katarismo: building generative new worlds with LLMs; How to expose any private service outside your headscale network; tags: headscale tailscale wireguard internal"/>
