Fix: add Gon variables to confirmations

related issue #1071 (closed)

upstream MR and it's duplicated with Sets Gon variables in response to requests with invalid reCAPTCHA

why?

JH Captcha is not working on users/confirmation page when trying to resend email confirmation due to the Gon variables are not available on the create action of ConfirmationsController after form submit.

This render action: 'new' only renders views without running any code in that action, that's why the Gon variables are not shown according to Rails docs.

This change will effect the create action of two controllers since the check_recaptcha method are used in app/controllers/passwords_controller.rb and app/controllers/confirmations_controller.rb.

What does this MR do

• Change render action: 'new' to redirect_to action: 'new'
