[New Quizzes] Allow addition of new questions to Item Banks immediately after creation

Problem statement:

If a new item bank is created from within the New Quiz builder, there is no option to add questions immediately. eg. After creating a new question bank, you must first exit the new bank, click the kebab menu and select Manage Item Banks, select the bank you just created, then you can now click the +New button. OR, Exit the newly created Item Bank, click the Return button, Click the Item Banks menu item, click the Item bank you just created, then you can now click the +New button.

Proposed solution:

After creating a new item bank, the user should be able to see and use a +New button in order to add new questions to the Item Bank.
