Subject: [PATCH] docs: Fix Fedora Repository, Icinga DB, SELinux

With Fedora 41, DNF was upgraded to version 5, breaking the command line
API of "dnf config-manager"[^0]. Unfortunately, DNF 5's addrepo does not
work with a simple URL anymore, but requires to construct a .repo file.

Furthermore, no information about trusting the Icinga signing key was
available, resulting in one being unable to install packages. This was
already the case for Fedora 40, still using DNF 4.

Since we are building Icinga DB for Fedora, I have included Icinga DB
documentation for Fedora. Otherwise, this section was empty.

Finally, the icingadb-redis-selinux package was mentioned for
distributions were we started to build SELinux packages for[^1].
