Rework YouTube list again

I'm moving to self-hosting this site and building it from my self-hosted
code repo and CI, which won't have access to my FreeTube subscriptions
when it builds. To get around this, I've moved to a script that will
snapshot my local FreeTube subscriptions to a JSON file. I'll commit this
file, and it can be used in the build on CI.

-I can't think of any particular trends or bubbling interests that contribute to the latest changes here. There aren't many new subscriptions, so most of the changes are a result of my pruning subscriptions I was no longer watching regularly.
+I've made another change to the way this page builds in moving to building on CI since that ☝️ blog post was written. It's still basically the same script, but instead of running during the build, I run it on-demand on my computer to snapshot the current state of my subscriptions and commit that data file to the repo. That file is then used by the build in CI to create this page.
+
+Continuing to prune channels I don't watch regularly anymore. I've continued to unsubscribe from some tabletop channels since I'm not super engaged with that hobby right now. That's not the only category that's seen pruning, but it's the most prominent one.
 
 ## Key
 - 👀- Instant watch
 - 🤌- Online video virtuoso
 - 😌- Good for sleepytime (This doesn't mean the content is bad, just that it's relaxing.)
