Remove table caption number

Since atlas automatically adds these, we should ensure they're removing
during processing.

This commit also contains some other misc. cleanup and the explicit
addition of a table into our "example book."

 <p>Of course, sometimes a pagebreak is needed. If it’s a paragraph, you can do something like the following:</p>
 <div class="highlight-html notranslate"><div class="highlight"><pre><span></span><span class="p">&lt;</span><span class="nt">p</span> <span class="na">class</span><span class="o">=</span><span class="s">&quot;pagebreak-before&quot;</span><span class="p">&gt;</span>
 Just like in a regular HTML book!
