Docs: Drop inline callouts (#1270)

Drops the inline callouts from the docs. This is when you write `<1>`
anywhere but the end of a line. Asciidoctor doesn't support them and
we'd very much like to move to Asciidoctor to generate the docs because
it is being actively maintained.

 TIP: Hive is case **insensitive** while {es} is not. The loss of information can create invalid queries (as the column in Hive might not match the one in {es}). To avoid this, {eh} will always convert Hive column names to lower-case. 
 This being said, it is recommended to use the default Hive style and use upper-case names only for Hive commands and avoid mixed-case names.
