Adding pandoc-secnos to the build environment.

[matthewturk]

In conjunction with https://github.com/manubot/manubot/pull/334 , this makes it possible to add section references to a manuscript. I have not updated the github hash for manubot referenced in the build environment, but will if/when that pull request is accepted.

A sample build of this is now in the yt paper build where you can see the number of sections referenced. I did note that all the sections are part of part 1, which I suspect might be an issue with the fact that I seem to be using ## as the base section number. That's probably fixable somehow on our end.

It would make sense to merge https://github.com/manubot/manubot/pull/334 first so we can update the manubot version in the environment here

Yes, can upgrade manubot to manubot/manubot@fb3950460ea2ce2c5e17e7fcffeec1bb75b0d822

I'm in favor of adding pandoc-secnos if we think it's unlikely to break anything. For manuscripts without any @sec:... references, I'm hoping this filter will essentially do nothing.

Unfortunately, the pandoc-xnos suite hasn't been receiving frequent maintenance. So switching to pandoc-crossref is probably the right move for Manubot. However, the syntax is similar, so merging this should not interfere with switching.
