feat: adds landing page scaffolding

[Eein]

What

Adds the landing page scaffolding for games list and the side about panel.

Have a couple of common test cases to verify rendering doesn't look weird.

These components can likely be more atomic, but would make more sense when styling.

Since intitial commit:

• added getLeaderboards to apiClient (this does not include the use of queries yet)
• cleans up some responsive design bits
• uses key for v-loop
• Removed: adds leaderboardgg colors to extend in tailwind.config.js - this is currently set to override, as the design team may want something else down the road. they are named very specifically as to not override the existing colors
• update: removes unnecessary interaction for scaffolding

Remaining Work

• Use actual links for the leaderboards
• temporary styling to make it more cohesive
• Mock backend tests

Link to Issue

I appreciate the Leaderboard names lighting up on hover but it would be great if there was some way to tell that they were clickable links without having to hover over them. Maybe style them with an underline?

Rebased, and made the changes requested -

Removed the mocks completely since this isn't doing any integration tests - more or less copy pasted from elsewhere which is why it was the way it is.
