Description of problem: DNF5 shows warnings on package upgrade at the erase stage. For example:

`[6/6] Erasing intel-media-driver-0:24.2.5-1.fc41.x86_64                                                   100% [==================] |  28.0   B/s |   9.0   B | -00m00s

Version-Release number of selected component (if applicable):

$ dnf --version
dnf5 version 5.2.6.2
dnf5 plugin API version 2.0
libdnf5 version 5.2.6.2
libdnf5 plugin API version 2.0

How reproducible: 100%


Steps to Reproduce:
1. Upgrade a package that has erase action

Actual results:

`warning: posix.fork(): .fork(), .exec(), .wait() and .redirect2null() are deprecated, use rpm.spawn() or rpm.execute() instead`

Expected results:

I would expect no warning, I don't know if fedora requires to update packages or what needs to be done, but the output may scare a lot of people when they will switch to dnf5
