Filter admin courses

[NIDHI2023]

Summary

• Adds a selection option for courses by semester to admin page
• Defaults to the current semester in the codebase
  • seems to be SP23, not sure if that's supposed to be updated?

• Displays Archived Courses section only for default semester, only displays filtered courses for rest of the semesters
• Changed "create course" button theme to match QMI theme more

Dependency Changes:

• run yarn add @mui/material @emotion/react @emotion/styled

Test Plan

-Check if all the desired semesters are available in the dropdown
-Check if the admin page loads the expected default semester, and the archived courses are only visible for this semester
-Check if the correct courses are displayed for each semester
-Check if the "Other" category displays any extraneous courses
-Check if creating a new course while the courses are in their filtered display properly shows up

Checklist

• [ x] I have updated the documentation accordingly.
• My PR adds a @ts-ignore

Functionality looks great, thanks for getting this working so quickly! This will definitely help us navigate the admin page a lot more easily.

Could you also mention in the PR description the dependency changes you made? e.g. the commands you may have run to change what's in the yarn.lock file. Some changes like using sass instead of node-sass were already merged into master, so I just want to double check that the dependencies are correct. Also, be sure to resolve merge conflicts and the pipeline failing issues (lmk if you need help with either of those, might be confusing).

I'll also add more code comments sometime tomorrow + we'll loop in the designers to see if they have any suggestions.

Could you try making the filter selection background white so that it doesn't blend in with the grayish page base color too much? There should be an option to do that. A bit wider by default as well.
