Add Help and Syntax for Jetpack shortcodes

[bobbingwide]

For WP-a2z we need to document the syntax and help for Jetpack's shortcodes. We need to complete the work previously started for Jetpack.

According to the help for shortcode embeds Jetpack also supports [cartodb], [codepen] and [recipes]. I can't find the first two and the shortcode for recipes is [recipe]. Note: recipe has a number of nested shortcodes [recipe-notes], [recipe-ingredients] and [recipe-directions].
