Add some help for fedora installation (from Fedora40 plasma)

[rloutrel]

Description

Add information for Fedora users: since no official client package is provided, a lot will have to go through those steps.

I am still facing issues at the compiling step, but at least dependencies are installed. I will update once compile/install is working.
