[Stable-10.0.2 0/1] Patch Round-up for stable 10.0.2

[Stable-10.0.2 0/1] Patch Round-up for stable 10.0.2

[Michael Tokarev]

The following patches are queued for QEMU stable v10.0.2:

  https://gitlab.com/qemu-project/qemu/-/commits/staging-10.0

There's a single revert of a commit in 10.0.1 which should not
be there in the first place, as a quick fix.

Thanks!

   Revert "Drop support for Python 3.8"

[Stable-10.0.2] Revert "Drop support for Python 3.8"

[Michael Tokarev]

This reverts commit 3d5b2f81fbc6b96b70271af1820674731a441ff7.

It should not be in 10.0.x branch, since we do support python 3.8
in 10.0.

python.docker to Fedora 41, otherwise the job will fail.
