    Update nano config for adoc files
    
    en/books/fdp-primer/book/#editor-config-nano
    
    section still refers to the old xml syntax. This patch updates the
    config to support adoc documents. Additionally:
    - The syntax highlight is collected from different locations in the web
    - Remove line-wrapping related stuffs as in ASCIIDOC we can have longer
      lines as there is a rule "one sentence per line".
