Hugo looks for the list/single templates of a taxonomy in `/layouts/taxonomy`, not `/layouts/taxonomies` as correctly mentioned in [this doc page](https://gohugo.io/templates/list/). This change is simply a minor reconciliation.
This commit adds a work flow aroung GoReleaser to get the Hugo release process automated and more uniform:
* It can be run fully automated or in two steps to allow for manual edits of the relase notes.
* It supports both patch and full releases.
* It fetches author, issue, repo info. etc. for the release notes from GitHub.
* The file names produced are mainly the same as before, but we no use tar.gz as archive for all Unix versions.
* There isn't a fully automated CI setup in place yet, but the release tag is marked in the commit message with "[ci deploy]"
Fixes#3358
For pages with translations, add links with hreflang attributes to the
default sitemap template. This helps Google to show the correct
language page in its search results. The syntax used is based on
Google's example at [1].
Also update the sitemap template docs to reflect the changes in the
default template.

This commit also adds a new command, docshelper, with some utility funcs that adds a JSON datafiles to /docs/data that would be a pain to create and maintain by hand.
Fixes#3242
Livefyre.com is down.
Livefyre was integrated into Adobe's offering.
The product is now called Adobe Experience Manager Livefyre.
Wikipedia points to web.livefyre.com which redirects to the link I provided in the commit.
This page was a real chore chore on the POC. In the event that a new doc site won't be approved by v20, this will at least clean up the broken links I found during my audit. I would like to eventually create this as a [data file](https://github.com/spf13/hugo/pull/2508#commitcomment-18705617) since md tables get unwieldy pretty quickly.
