Summary:
The goal of this PR is to place greater emphasis on the blog as a destination.
The dark Hero from the landing page is now present in the blog as well, and the content is front and center.
The sidebar has been removed. It is not necessary to show a list of recent blog posts in the sidebar when the blog landing page shows the same number of posts along with short excerpts.
The prev/next links have swapped positions, and will now display "Older posts" and "Newer posts".
The excerpts have been stripped of formatting and they are now consistent across the blog landing page and the OpenGraph metatags. Fixes#10597.
A signup form for the new React Native newsletter has been added to the footer.
