Update fontawesome

It looks like the package we are using was not updated for a long time (5 years) https://www.npmjs.com/package/font-awesome

I dont really understand this package, but it looks like there is a version 5 freely available.

• @fortawesome/react-fontawesome (https://www.npmjs.com/package/@fortawesome/react-fontawesome)
• @fortawesome/fontawesome-free (https://www.npmjs.com/package/@fortawesome/fontawesome-free)

What about an update, and in this case, any idea if we will have stuffs to fix?
