Add 'Trash in, Treasure out' blog post

[hdoordt]

Companion repo: https://github.com/mainmatter/trash-in-treasure-out/

Todo:

• add links to steps
• Add short explanation of title (parody on 'garbage in, garbage out')
• Do something about the mermaid diagram. Support for that on the site would be cool. @marcoow any ideas?

I don't know what's going on with CI, but it doesn't seem like the failing jobs are caused by this addition?

about Mermaid, you can ask @umbrellas – I guess there should be a plugin or so for 11ty

This is a great post! Let's get it out asap. @IdeliaRisella can handle things like adding og:image, scheduling the release, etc.

If we can't figure out a solution for supporting Mermaid diagrams easily, let's just use an image instead for now.

@marcoow I have already sent the og:image to @hdoordt yesterday, let me know if you need anymore help. Meanwhile, I can help prepare the publication on social media on Friday.

I replaced the mermaid source with a rendered SVG, and did some other fixes.

I added the metadata as suggested by @BobrImperator, but CI still seems to be failing. I'm gonna need some help with this.

@hdoordt you need to add your author profile image (named hdoordt.jpg) in https://github.com/mainmatter/mainmatter.com/tree/master/static/assets/images/authors

@marcoow Most of the checks seem to pass right now. The 'Craw links' check seems to fail on some image that's not related to this PR not being there, and the others need manual interaction.

I looked at the preview and it looks good now to me
