Publish smartdown version of Student Finance Forms 

The smartdown implementation of student finance forms has been tested
and are feature complete with the original rb/yml implementation.

**Smartdown version**
* Remove the -transition suffix, which distinguished it from the
  original version
* Change status to published

**rb/yml version**
 - remove the logic, copy and test
 - do the same for an old v2 that's knocking around

If you could add a LGTM, rather than merge, so I can merge myself.
