Quiz management: Add "Update resources" option to Options dropdown

[nucleogenesis]

Overview

Peter noted during testing that it is not clear how/where to go back and update your resource selection after having the "+ Add Questions" button removed by the questions list.

The flow requires the user to go to "Options -> Edit Section" to open the side panel, then click "Change resources"

We'll improve this flow a bit by adding that option to the Options menu

Acceptance criteria

• Add "Update resources" string to the enhancedQuizManagementStrings file
• Add option "Update resources" with a plus-sign icon to the list of options (defined here)
• Update this handleActiveSectionAction method so that it also checks against the string used for the label and routes the user to the select QUIZ_SELECT_RESOURCES route
