Course code in fuzzy search

[MinhxNguyen7]

Description

• Functionality to search for a course code in fuzzy search.
• The easiest way to do that would be to see if the query is a five-digit number and say "search for section xxxxx"
• The better UX would be to show the section itself in the search suggestions.
  • This would necessitate changing the fuzzy search drop-down and re-implementing fuzzy search on a per-term basis (which would probably be a nicer experience) because section codes are resused.

#1129 was a broken implementation and has been reverted

We need to think about how to do this without increasing the bundle size and memory usage 20 times
