Migrate to react-icons

[arkid15r]

Describe the solution you'd like

We recently added custom icons, it seems we could just use react-icons instead.
Import font awesome icons from the new package.
Replace the custom icon (sun) with similar one.

Are you going to work on implementing this?

• Yes
• No
