Build Tutor Leaderboard component

[Otaiki1]

Build the tutor leaderboard component, design shown here

Note that

• You wont be building the sidebar component or the tabs component at the top of the design
• The file should be situated at src/pages/tutor/Leaderboard.tsx
• For better context this is the only thing you are building

• The boxes have to be built dynamically as their components will be reused , same thing with list as it will be populated so they can be two seperate components , note that the student list component should auto sort whatever array is passed into it

• Drop working PR within 2 days and it should reference the issue number it is closing
