* Add tr as child of thead in HTML tables

It is invalid HTML for th to be the direct children of thead

Signed-off-by: Kévin Commaille <zecakeh@tedomum.fr>

* Remove unnecessary HTML code end tag

Signed-off-by: Kévin Commaille <zecakeh@tedomum.fr>

* Avoid nesting p HTML elements

A p HTML element cannot contain other block elements,
so the "parent" element is closed when the first "child" one is opened.

We need to use Page.RenderString with options
to force Hugo to keep the wrapping p elements
even if the content contains a single paragraph.

* Add missing HTML details end tags

* Replace HTML a self-closing tag with start and end tags

The a element start and end tags are mandatory.
