This change removes RelatedArticles from beta features.
It repurposes the BlacklistSkins config to be a whitelist that describes
when related pages should be shown in the footer.
To avoid enabling related pages on desktop, this depends on a config
change that makes use of the new configuration option.
Simplify browser tests to reflect the new status quo.

Hide the related articles from the sidebar if ReadMore is enabled.
Otherwise leave as is because it's used in WikiVoyage.

If the page has related articles, is in mainspace, isn't the main page,
and the output is being rendered with the MinervaBeta skin then a
"Related Articles" section is added to the page just before the footer.
Separate loading the information necessary to render the pages, choosing
the renderer, and rendering the data so that multiple skins - currently
Minerva and Vector per the mocks - not just multiple resolutions can all
be handled the same way:
* The bootstrap script (ext.relatedArticles.readMore.bootstrap/index.js)
for fetches the page image and Wikidata description; loading the
renderer module; and, finally, notifying the renderer module that it
should render the data, which it does by emitting
"ext.relatedArticles.readMore.init" event using mw#track
* The Minerva renderer subscribes to the event and, when it's fired,
renders the data by passing it to the WatchstarPageList view
