You can now run `nix build '.#docs'` to build HTML documentation
documenting every single option on nixvim! Fortunately, thanks to
the 'description' field, most options are already documented, but
there are still a fair few that need documenting.
I will be taking care of those in the next few days. When those are
done, I will find a way to automatically rebuild documentation on every
repo push, and also add a PR hook requiring documentation.
Additionally, I will try to find a way to have per-page plugin docs.
