[help] render user documentation once on startup

Currently we have two kinds of user documentation:

* the about page[1] which is written in HTML and part of the web
  application and can therefore link instance-specific pages
  (like e.g. the preferences) via Jinja variables

* the Sphinx documentation[2] which is written in reStructuredText
  and cannot link instance-specific pages since it doesn't know
  which instance the user is using

The plan is to integrate the user documentation currently in Sphinx
into the application, so that it can also link instance specific pages.
We also want to enable the user documentation to be translated.

This commit implements the first step in this endeavor (see #722).

-  <p>
-    SearXNG is a fork from the well-known <a href="https://github.com/searx/searx">searx</a>
-    <a href="https://en.wikipedia.org/wiki/Metasearch_engine"> metasearch engine</a>,
-    aggregating the results of other <a href="{{ url_for('preferences') }}">search engines</a>
-    while not storing information about its users.

-  <h2>Why use it?</h2>
-
-  <ul>
-    <li>
-      SearXNG may not offer you as personalised results as Google, but it doesn't
-      generate a profile about you.
-    </li>
-    <li>
-      SearXNG doesn't care about what you search for, never shares anything with a
-      third party, and it can't be used to compromise you.
-    </li>
-    <li>
-      SearXNG is free software, the code is 100% open and you can help to make
-      it better.  See more on <a href="{{ searx_git_url
-      }}">SearXNG sources</a>.
-    </li>
-  </ul>
-
-  <p>
-    If you do care about privacy, want to be a conscious user, or otherwise
-    believe in digital freedom, make SearXNG your default search engine or run
-    it on your own server
-  </p>
-
-  <h2>Technical details - How does it work?</h2>
-
-  <p>
-    SearXNG is a <a href="https://en.wikipedia.org/wiki/Metasearch_engine">metasearch engine</a>,
-    inspired by the <a href="https://beniz.github.io/seeks/">seeks project</a>.
-
-    It provides basic privacy by mixing your queries with searches on other
-    platforms without storing search data. Queries are made using a POST request
-    on every browser (except Chromium-based browsers*).  Therefore they show up
-    in neither our logs, nor your url history. In the case of Chromium-based
-    browser users there is an exception: searx uses the search bar to perform GET
-    requests.
-
-    SearXNG can be added to your browser's search bar; moreover, it can be set as
-    the default search engine.
-  </p>
-
-  <h2 id='add to browser'>How to set as the default search engine?</h2>
-
-  <p>
-    SearXNG supports <a href="https://github.com/dewitt/opensearch/blob/master/opensearch-1-1-draft-6.md">OpenSearch</a>.
-    For more information on changing your default search engine, see your browser's documentation:

-    <li>Chromium-based browsers <a href="https://www.chromium.org/tab-to-search">only add websites that the user navigates to without a path.</a>

-  <h2>How can I make it my own?</h2>
-
-  <p>

-    the <a href="{{ searx_git_url }}">SearXNG project</a> and
-    run it yourself!
