Create the Leaderboard component

Is your feature request related to a problem? Please describe.
The leaderboard component is similar to the material-table components. Create the component.

Describe the solution you'd like

• Material table provides a component that has the search feature. Make sure to use the particular one and make the adjustments as required.
• It also has good provisions to update the styles of literally each and every part of the component. Go through the docs well and update the styles as designed.

Addition Note

• We are going to follow a pattern for this which is very standard. So the idea is to separate all the logic from the UI stuff.
• Since this component requires heavy integration with firebase, it makes sense that a wrapper component containing all the firebase logic is created and another component that has all the styles and JSX is created.
• As of now, in this PR, just create the style component but do keep in mind this architecture and code accordingly.
