Backend: Update Kramdown Version

[harding]

Updates to a newer version of Kramdown, the library used to convert Markdown to HTML. A diff of the generated website using the previous version to the new version is available here. There are only two changes that I see:

1. Automatically-generated table of contents for the various dev docs now have an id attribute assigned to each list item. Every id starts with markdown-toc- so I doubt there are any conflicts with previous ids and I don't see any issues.
2. In plain-text paragraphs and list items converted to HTML by Kramdown, trailing whitespace is now removed. I confirmed this does not apply to anything inside pre tags. I also confirmed that it only applies to trailing whitespace.

Not visible is that the old version of Kramdown has problems with HTML <button>, which I ran into while working on a separate branch. This update to the newer version fixes that.

Note: when merged, this PR will be the first test of the new automatic library upgrade feature on the build server. I'll be standing by to fix any problems. @saivann and anyone else who has previously built the website locally will need to run bundle install from their local repository directory to install the newer version of Kramdown.

Untested LGTM, thanks!

Post-merge note: I verified that the site built correctly with the updated library. There was no problem with the update mechanism.
