feat: add spotify urls to all episodes

[msmps]

Description

As part of some ongoing work here to bring syntax to the listeners fingertips via a Raycast extension...

I wanted to be able to launch each episode directly in the Spotify application. However, I soon realised this was not possible without the Spotify URI. This kicked off a weekend of work for me to figure out how to get the URI from Spotify for each of the episodes, given that there is currently no real relationship. I have written a tool (which I will link shortly for reference), to parse each markdown file and create a hashmap using the show date as the index and the episode/file information as the value. The tool then calls out to the Spotify API in batches to pull the episodes from Spotify and using the same show date, fetches the matching episode from the hashmap and updates the frontmatter of the markdown file.

I hope this is ok @wesbos @stolinski

@msmps is attempting to deploy a commit to the Syntax Team on Vercel.

A member of the Team first needs to authorize it.

Thanks for working on this! Reviewing 765 changed files is quite a lot though.

Could you make a PR with only the schema / page updates, with maybe 1 markdown file updated for us to test and then link us your tool so we can add the links to the rest of the markdown files ourselves?

Thanks, folks! I appreciate the kind words! Of course, @w3cj, I've updated this pull request to only include the bare minimum for testing 😃 I'll upload my tool and return with a link! 👍

I've pushed up the tool @w3cj; you can find it here! If you need any help with anything, feel free to connect with me on X or something! I look forward to getting these changes live! 😃
