Fix glitch in completed quiz report sections displaying incorrect values

[LianaHarris360]

Summary

This pull request updates AttemptLogList.vue to display the correct attempt logs and correct/incorrect icon within each section.

The computed property attemptLogsBySection has been added to generate and return the attempt logs within every section.

The computed property attemptLogsForCurrentSection has been updated to use attemptLogsBySection to access the correct attempt log based on the selected section + question pair when in mobile view.

The attempt log object passed to AttemptLogItem has been updated to use attemptLogsBySection as well.

Before:

AttemptLogsBefore.mov

After:

AttemptLogsAfter.mov

Fixes #13101

Reviewer guidance

1. Assign a quiz with at least 2 sections to a learner
2. Complete the quiz by giving only correct answers in one of the sections and only incorrect answers in the other.
3. Observe the quiz report either as a learner or a coach

Code looks good to me. I tested locally and the correct info was shown for each section
