Subject: [PATCH] E.19: clarify that `finally` is from the GSL (#1936)

When I stumbled upon E.19 "Use a `final_action` object to express
cleanup if no suitable resource handle is available" I was hopeful
that this `final_action`/`finally()` thing is from the STL, but, alas,
it isn't.

Make it clear that `finally` is a GSL construct.

 ##### Reason
 
-`finally` is less verbose and harder to get wrong than `try`/`catch`.
