Switch to DNF5

[xerxes2]

So I have had weird segfaults with DNF lately and both DNF and RPM are outdated so it'll probably be fixed when they get updated. But just when I was sniffing around I found out that there's a new DNF incoming that will eventually replace the old one. And cauldron already got it packaged. I've been testing it now for a few hours and it seems to work just fine. You just use it as "dnf5" and almost all the old switches will work. Good work of the package maintainer to package it so early.

Added it to the wiki page. https://wiki.mageia.org/en/Using_DNF#Next-generation

Thank you for adding

And thank you for reworking the wiki page a bit. It looks much better now. Yeah so I've been running DNF5 now for a few weeks and it seems to work just fine. It's a lot faster than the old one and got multi-threaded downloads too. Not that speed is that important anymore really as cpus are extremely fast anyway now but it doesn't hurt either.
