Fix: add missing import 'locale'

Fix formatting of Groups of Groups

* Prompt had to be moved up, as it needed to be done before the first
  templating of the play occurs, otherwise vars_files won't be templated
  properly
* Fixed a bug related to an earlier fix of vars_files incorporating
  extra vars to do the templating of the file name

Fixes #11404

The example in the Groups of Groups section was being rendered as a quote.
Switching to the `::` notation causes it to render as preformatted text instead.
This could have also been done with a `.. code:` block, but I chose to be
consistent with other sections in the document.
