Switch to using submodule for content

Prompted by the discussion with Bryan Hogan in the comments of my partial clone post (thanks for the nudge, Bryan, and for your helpful writeup!)

Looks like it worked! Updated the content repo and kicked the build here to see if it'll always pull main from the content repo. (If I'm understanding things correctly, it should, because of how I've set up the .gitmodules file.)

EDIT: It did not---turns out the setting in .gitmodules only affects what happens when you run git submodule update --remote.

I got it to pull the latest main on the submodule by adding a step to the deploy pipeline. But I don't like that the repo can get behind still, even though it doesn't affect anything, and I'm not too keen on the need to manually update the submodule in my local copy of the repo.

Overall, though, I think this is good enough. It's so nice to be able to have my writing in a private repo! And now I can check out the content repo by itself on my writing laptop instead of needing a partial clone.
