Add question number to ControlBar

[jiachen247]

Previously, when students do the missions/quizzes we have no clue how many questions the mission contains.

This makes it much easier to track progress when doing any kind of assessment.

@jiachen247 Thanks for the initiative! This looks good so far, but I feel that with the inclusion of question numbers, the logic behind having previous/next/return buttons can be shifted to the ControlBar. This means that AssessmentWorkspace and GradingWorkspace only need to pass the question number and max question number, and the previous/next button logic is taken care of using the question number information inside ControlBarProps. Could you implement this for this PR? Do let me know if you have any doubts

@remo5000 yepps!!! totally agreee - cleaner this way :-)

have shifted responsibility of flow control entirely into the control bar.

hope it helps!!

LGTM

@jiachen247 Whoops, it seems like you pushed without formatting and updating the tests -- could you run yarn format and yarn test to resolve these? I'll merge it after

[jiachen247]

@remo5000 great! have formatted the code and have updated the failing snapshots :-)

[remo5000]

@jiachen247 Merged, cheers!

[jiachen247]
