It's still work in progress but I'm removing draft status so that I can enable this branch on readthedocs and we can test links there.

Looks like that's working, e.g., https://taxpasta.readthedocs.io/en/docs-links/tutorials/getting-started/. So now I just need to go through all links in all markdown files 😝

Thank you for the offer. I hope I caught all of the necessary changes using a pattern search. Just need to fix this one link now.
