Fix example when processed as asciidoc (elastic#116)

The `fields` entry example consists of a dictionary surrounded by
quotes. This causes problems when the example is used for documentation
in asciidoc format, as it is interpreted as an escaped attribute, and
the docs generation fails because it cannot find a "key1" attribute.

Fixed by removing the quotes.
