Oops... I missed that wic is executed inside the chroot. We can try to
apply the same patch and hope that code path requiring 3.8 is traversed
(as before).

But it is anyways rather suboptimal to execute wic inside the chroot.
Changing this is out of scope for now, but with the current design we
either can't safely update bitbake (even a stable branch) or we will
lose distro support from time to time.

Does the CI pass if we just re-apply your patch?
We definitely need bitbake 2.8.1 to support Python 3.14, so eventually
we have to update.
