fix(form): auto open form modal JS code is not working

[ravinderk]

User Story

As an admin, I want form modal to open automatically if the parameter set in URL so that donor can donate more easily.

Current Behavior

Form modal does not open when form-id and payment-mode set in URL ?form-id=188&payment-mode=manual

Expected Behavior

Auto-open form modal if form-id and payment-mode set in URL

Solution

Because of webpack, the previously global function is not accessible anymore we can make them accessible by window.{function}.
