[bug#47607] [PATCH] website: header: Make dropdowns width vary according to their content

Hi,

Currently, a menu item that is longer than its container box is broken into lines and looks as separate items. For example:

This change makes submenus as wide as their widest item:

Subject: [PATCH] website: header: Make dropdowns width vary according to their
 content.

This change avoids breaking menu items in separate lines when they are
longer than their container box. When they are wrapped, they become
hard to read because they look like two separate items.

The "Medios" menu in the Spanish version of the website, equivalent to
the "Media" menu in the English version, illustrates this odd behavior.
It looks as if there were four menu items, when there's actually two.

* website/static/base/css/navbar.css (.dropdown:hover .submenu)
  (.submenu:focus-within): Make submenus adapt to their widest item.
  (.hline): Limit its width so that submenus are not as wide as the
  original separator image.
