Replace `dnf update` with `dnf upgrade`.
The `dnf upgrade` is better than the `dnf update`. The `dnf update` works, but
it is a deprecated alias of the `upgrade`.
```
$ rpm -q dnf
dnf-4.13.0-1.fc36.noarch
$ man dnf
...
Upgrade Command
Command: upgrade
Aliases: up
Deprecated aliases: update, upgrade-to, update-to, localupdate
