In templates/zerver/api/main.html, since the current context isn't
passed to render_markdown_path when rendering an article,
render_markdown_path doesn't have the context to render values such
as api_url. This commit makes sure that it does by passing a dict
called api_uri_context to render_markdown_path when rendering an
article.
In addition to decreasing the excessive number of bundles we had, this
will set us up to fix rendering of code blocks when clicking the
sidebar links in the /api-new site.
This commit allows for the /api-new/ page to rendered similarly to our
/help pages. It's based on the old content for /api, but we're not
replacing the old content yet, to give a bit of time to restructure
things reasonably.
