Remove redundant navigation arrows from the Maps page

[jwang-101]

Description
If you look at any modern maps application, moving around the map is usually handled with dragging via a mouse or finger. However, on our map, there also exists 4 arrow buttons pointing up down left right in the bottom right corner.

Since you need a mouse to use a computer, these buttons are redundant, as anyone who would be able to click these buttons would be able to move the map with their mouse instead. Thus, we should remove these redundant buttons for UI minimalism.

For reference, look at the bottom right corner of Google Maps and compare it to our website.

Tasks
