…DNF3 instructions as backup ## Description With the widespread adoption of DNF5, I propose updating the Docker installation documentation to reflect modern package management standards on Fedora. I noticed a previous attempt to do DNF5 documentation (referencing docker#21037) ended in failure because the addrepo command was used incorrectly, referencing an older DNF3-4 notation instead of proper DNF5 `addrepo --from-repofile=` notation. I have corrected this mistake and suggest this quick documentation update since Fedora 42 will be in beta soon, encouraging more users to update to 41/42, where DNF5 will be the standard format going forward. I have also included the older command for legacy systems so that both cases are covered. I tested this change on a Fedora 41 KDE VM, and it works as expected. Since DNF5 is a complete rewrite in C++, replacing the Python-based DNF3/4, it offers improved performance and memory efficiency. Updating the documentation will help prevent confusion for users writing installation scripts while ensuring compatibility with the latest Fedora releases. ## Requested Review Please double-check to verify that I completed the URL correctly following Fedora's documentation standards, so it will be formatted properly on the website! Thanks!

I think we should keep the "old" commands until Fedora 40 reaches EOL, that way we don't have to describe two separate ways to do this (as the installation guide already is quite complex due to many steps)
