@AhemNason we had a problem with some of our dependencies and it broke the GitHub action that tests the build. In this PR, I've updated the dependencies. But I want to make sure that you can still build the docs hub, so that we don't accidentally get you into a tricky position.

To test this out properly, can you:

1. Clone my repository from scratch. (To make sure the dependency packages are fresh.)
2. Check out my branch (git checkout dependencies).
3. Run bundle install to install the dependencies.
4. Run bundle exec jekyll build to build the site.

Let me know if that all goes smoothly for you. If not, we'll hold off on these changes until we have time to work through the issues together.

Went smoothly, with no issues!
