FIX Display rules for page breaks/editable form steps now works again

Browse Source 
This was previously broken in a regression from https://github.com/silverstripe/silverstripe-userforms/pull/575
where the fields themselves could still be toggled, but the jQuery event dispatches for the form steps
were removed. This pull request re-introduces those jQuery event triggers when hiding and showing
editable form fields via display rules.
