Update to fontawesome 6.0+ to pull in new Fedora logo

[MoralCode]

I noticed that the download page is still using the old fedora logo, which seems to be coming from fontawesome v5. Fontawesome v6 has an updated version of this logo with a cleaner look.

Wanted to file this just to document this desire to update the logo as I don't currently have the time to make the contribution myself and figured it may be a good easy fix for a new contributor, or something to lump into the next dependency refresh or something.
