Subject: [PATCH] Add a canonical link to every page

The Netlify production build serves a second, indexable copy of the site
at nwborg.netlify.app, and pages can also be linked with tracking
parameters. A canonical link tells search engines that the nwb.org
address is the one to index.

The paginated news list is left out. Hugo gives every page of that list
the same `.Permalink`, so a canonical link there would point page 2 at
page 1.
